    Some Important Master screens for PMS

    Last year I was involved in developing an independent system for PMS using VB6 with sql server 2005. I really enjoyed myself and love to work/complete that project. One of my best period in my life. But unfortunately, we could not able to market the product because of VB6 no longer used widely in the industry.

    Physician Quality Reporting System - PQRS

    Let me just summarized the information which i understood clearly about PQRS . The following information are taken from different websites and some of them of my own question and answer Eye rolling smile. And also I just want to have a reference about this, so that when I get chance to implement this, I can always come and refer here. At the end, I just summarized my thought on how we can implement in the EMR PMS Application.

    Hibernate Validator - Capture the exception using Utility Class

    Hibernate Validator - Creating custom constraints @Required – Example 4

    In this post, we will see how we can create our own custom constraints tailored to our specific requirements.

    Hibernate Validator - Creating custom constraints–Example

    In this post, we will see how we can create our own custom constraints tailored to our specific requirements.

    Hibernate Validator Example 2

    In this example, we will see some more validation constraints such as @email, @past, @length, etc. And also we will also define custom error message.

    Hibernate Validator Examples

    Let us some examples for Hibernate validator
    Here is the introduction notes from the hibernate documentation
    Bean Validation standardizes how to define and declare domain model level constraints. You can, for example, express that a property should never be null, that the account balance should be strictly positive, etc. These domain model constraints are declared in the bean itself by annotating its properties. Bean Validation can then read them and check for constraint violations. The validation mechanism can be executed in different layers in your application without having to duplicate any of these rules (presentation layer, data access layer). Following the DRY principle, Bean Validation and its reference implementation Hibernate Validator has been designed for that purpose.
    The integration between Hibernate and Bean Validation works at two levels. First, it is able to check in-memory instances of a class for constraint violations. Second, it can apply the constraints to the Hibernate metamodel and incorporate them into the generated database schema.
    Each constraint annotation is associated to a validator implementation responsible for checking the constraint on the entity instance. A validator can also (optionally) apply the constraint to the Hibernate metamodel, allowing Hibernate to generate DDL that expresses the constraint. With the appropriate event listener, you can execute the checking operation on inserts, updates and deletes done by Hibernate.
    When checking instances at runtime, Hibernate Validator returns information about constraint violations in a set of ConstraintViolations. Among other information, the ConstraintViolation contains an error description message that can embed the parameter values bundle with the annotation (eg. size limit), and message strings that may be externalized to a ResourceBundle.
    Example 1:
    In the first example, we will see very basic not null constraint validation. Here is the Step by Step Tutorial.
    Example 2:
    In the second example, we will see some more constraint validation. Here is the Step by Step Tutorial.
    Example 3:
    In this example, we will see how we can create our custom constraint validation. Here is the Step by Step Tutorial.
    Example 4:
    In this example, we will see how we can create our custom constraint @Required. Here is the Step by Step Tutorial.
    Example 5:
    In this example, nothing is new, we will take care example 2 and will use the utility class to perform validationHere is the Step by Step Tutorial.

    Hibernate Validator Example 1

    In this example, we will see very basic validation @NotNull.

    MVVM–List Item–Hibernate–MySQL–Part 2

    In the part 1, we have seen, how to list the records from DB using ZK List box. Now let us go further and see how we can add new record and edit exiting record and update into DB.
    In this post, we will see how we can do the following stuffs
    1. Add new person by calling a model window in MVVM and update in the DB
    2. On Double click of the records in the list item, edit the existing record by calling a modal window in MVVM and update in the DB
    3. Then after edit and add, we will refresh the list. Note, after edit, we no need to do anything, because data binding will take care. But after adding new person, we will refresh the list using Global command

    List Item Double click event on selected Item

    In this example, let us see how we can handle the double click event on list item on the selected item.

    ViewModel Class Java Annotation @Init, @NotifyChange, @Command


    In following sections we'll list all syntaxes that can be used in implementing a ViewModel and applying ZK bind annotation.

    ZK MVVM CRUD - Part 3



    Previous Part 2



    In Part 2, we slightly change the retrieve of  objects by adding constructor. Now we will move forward. Let us take a look on the output as follows
    image
    Apart from the listing the records, we also have two search parameters such as Practice name and Show only active or inactive practices. So what we are going to do with this ? Well, if the list is big, then user has to move to particular page to locate the desired practice, instead of that we will filter the practice as soon as user starts typing the first few characters of the practice name. And also, by default we will show all the active (soft delete) records. If the user want to see all the records including deactivated, then on click of check box, we will also do that.
    So here are the conditions
    Case 1:
    If no character present in the Practice name filter text area and also Show only active is unchecked, then let us show all the records from the DB.

    Case 2:
    If some characters are typed in the practice name filter and check box is  unchecked, then show all active and inactive records for the practice whose first characters are matched with the filter text

    Case 3:
    If no character in practice name filter text area and check box is checked, then we will show all the active practices only.

    Case 4:
    If both the search parameters contains values, then we will retrieve the records accordingly.

    And also, we are going to Apply new ZK Bind Annotation such as @NotifyChange and @Command. Please refer here for examples in this subject. 
    And also very important, we are not going hit the database for each character is typed or check box is checked or unchecked. First time we will hit the DB to bring the records and then we will do all the filter locally.
    Step 1:
    From the View, we need to pass the value of Practice name text area and Check box state (checked or unchecked)  to the View Model to filter the record. So we will write the following getter and setter method.
    private String practiceStartWith;
    private boolean showOnlyActive;

    public String getPracticeStartWith() {
            return practiceStartWith;
        }
        public void setPracticeStartWith(String practiceStartWith) {
            this.practiceStartWith = practiceStartWith;
        }
        public boolean isShowOnlyActive() {
            return showOnlyActive;
        }
        public void setShowOnlyActive(boolean showOnlyActive) {
            this.showOnlyActive = showOnlyActive;
        }

    Step 2:

    Here is the modified PracticeVM.Java
    package UIVMs;
    
    import domain.Practice;
    import java.util.ArrayList;
    import java.util.List;
    import org.zkoss.bind.annotation.Command;
    import org.zkoss.bind.annotation.NotifyChange;
    import DomainDAO.practiceDAO;
    
    public class PracticeListVM {
    
        private List<Practice> AllPracticeInDB = null;
        private List<Practice> filteredPractices = null;
    
        private String practiceStartWith;
        private boolean showOnlyActive = true;
    
        public String getPracticeStartWith() {
            return practiceStartWith;
        }
    
        public void setPracticeStartWith(String practiceStartWith) {
            this.practiceStartWith = practiceStartWith;
        }
    
        public boolean isShowOnlyActive() {
            return showOnlyActive;
        }
    
        public void setShowOnlyActive(boolean pActive) {
            this.showOnlyActive = pActive;
        }
    
        public List<Practice> getprlist() {
            if (AllPracticeInDB == null) {
                filteredPractices = new ArrayList<Practice>();
                AllPracticeInDB = new practiceDAO().getListingItems();
                setShowOnlyActive(true);
                for (Practice item : AllPracticeInDB) {
                    if (item.getIsActive() == 1)
                        filteredPractices.add(item);
                }
            }
    
            return filteredPractices;
        }
    
        @NotifyChange("prlist")
        @Command
        public void doFilter() {
    
            filteredPractices.clear();
    
            /* if no filter characters and check box is un checked. Then get all */
            /* 0 and 0 */
    
            if ((practiceStartWith == null || "".equals(practiceStartWith))
                    && (showOnlyActive == false)) {
                filteredPractices.addAll(AllPracticeInDB);
    
            }
    
            /*
             * if there are filter characters and check box is un checked. Then get
             * filtered by filter text
             */
            /* 1 and 0 */
    
            if ((practiceStartWith != null && !practiceStartWith.equals(""))
                    && (showOnlyActive == false)) {
                for (Practice item : AllPracticeInDB) {
                    if (item.getPracticeName().toLowerCase()
                            .indexOf(practiceStartWith.toLowerCase()) == 0)
                        filteredPractices.add(item);
                }
            }
    
            /*
             * if no filter characters and check box is checked. Then get only
             * active practices
             */
            /* 0 and 1 */
    
            if ((practiceStartWith == null || "".equals(practiceStartWith))
                    && (showOnlyActive == true)) {
                for (Practice item : AllPracticeInDB) {
                    if (item.getIsActive() == 1)
                        filteredPractices.add(item);
                }
            }
    
            /*
             * Both Contains values i.e filter contains some text and check box is
             * checked
             */
            /* 1 and 1 */
    
            if ((practiceStartWith != null && !practiceStartWith.equals(""))
                    && (showOnlyActive == true)) {
                for (Practice item : AllPracticeInDB) {
                    if (item.getPracticeName().toLowerCase()
                            .indexOf(practiceStartWith.toLowerCase()) == 0)
                        if (item.getIsActive() == 1)
                            filteredPractices.add(item);
                }
    
            }
    
        }
    }


    Step 3:


    Here is the modified practiceList.zul

    <?page title="Practice List" contentType="text/html;charset=UTF-8"?>
    <zk>
    
        <window apply="org.zkoss.bind.BindComposer"
            viewModel="@id('vm') @init('UIVMs.PracticeListVM')">
            <div>
                <button label="Add Practice" />
            </div>
            <separator />
            <groupbox height="40px">
                <label value="Practice Name" />
                <space />
                <space />
                <textbox width="250px"
                    value="@bind(vm.practiceStartWith)"
                    onChange="@command('doFilter')" instant="true" />
                <button id="gobutton" label="Go" />
                <space spacing="20px" />
                <checkbox id="activechk" label="Show only active"
                    checked="@bind(vm.showOnlyActive)" onCheck="@command('doFilter')" />
                <space spacing="20px" />
            </groupbox>
            <separator />
            <listbox id="PracticeList" model="@load(vm.prlist)">
                <listhead sizable="true">
                    <listheader label="Practice Name" sort="auto" />
                    <listheader label="City" sort="auto" />
                    <listheader label="State" sort="auto" />
                    <listheader label="Zip Code" sort="auto" />
                </listhead>
                <template name="model" var="p1">
                    <listitem>
                        <listcell label="@load(p1.practiceName)" />
                        <listcell label="@load(p1.city)" />
                        <listcell label="@load(p1.state)" />
                        <listcell label="@load(p1.zipCode)" />
                    </listitem>
                </template>
    
            </listbox>
        </window>
    </zk>



    Step 4:


    Now we can run and play around both practice name filter and check box.
    The following is the execution flow

    1. An Instance will be created for our PracticeListVM
    2. Since we declared true value initially for showonlyactive, and also we bind our checkbox with showactiveonly, so first set method of showonlyactive will take place.
    3. Then our getprList  will take place because we bind our list to this get method.
