By using Bean Shell Form Binder, we are able to load and update our Environment Variable values by using a form.

Let's create a form with each Text Field to represent a Environment Variable in our app and set all the field id to the ID of the Environment Variable.

Then, click on "Properties" tab then set the "Load Binder" and "Store Binder" in "Advanced" page to "Bean Shell Form Binder".

Using the following script for "Load Binder".

import java.util.Collection;
import org.joget.apps.app.dao.EnvironmentVariableDao;
import org.joget.apps.app.model.AppDefinition;
import org.joget.apps.app.model.EnvironmentVariable;
import org.joget.apps.app.service.AppUtil;
import org.joget.apps.form.model.Element;
import org.joget.apps.form.model.FormData;
import org.joget.apps.form.model.FormRow;
import org.joget.apps.form.model.FormRowSet;
import org.joget.commons.util.LogUtil;
 
public FormRowSet load(Element element, String primaryKey, FormData formData) {
    FormRowSet rows = new FormRowSet();
    AppDefinition appDef = AppUtil.getCurrentAppDefinition();
 
    if (appDef != null) {
        EnvironmentVariableDao environmentVariableDao = (EnvironmentVariableDao) AppUtil.getApplicationContext().getBean("environmentVariableDao");
        Collection environmentVariableList = environmentVariableDao.getEnvironmentVariableList(null, appDef, null, null, null, null);
        
        //loop the result and add to FormRow
        if (environmentVariableList != null && environmentVariableList.size() > 0) {
            FormRow r = new FormRow();
            
            for (EnvironmentVariable e : environmentVariableList) {
                if (e.getValue() != null) {
                    r.setProperty(e.getId(), e.getValue());
                }
            }
            
            rows.add(r);
        }
    }
    
    return rows;
}
 
//call load method with injected variable
return load(element, primaryKey, formData);

 

Using the following script for "Store Binder".

import org.joget.apps.app.dao.EnvironmentVariableDao;
import org.joget.apps.app.model.AppDefinition;
import org.joget.apps.app.model.EnvironmentVariable;
import org.joget.apps.app.service.AppUtil;
import org.joget.apps.form.model.Element;
import org.joget.apps.form.model.FormData;
import org.joget.apps.form.model.FormRow;
import org.joget.apps.form.model.FormRowSet;
import org.joget.apps.form.model.FormStoreBinder;
import org.joget.plugin.base.PluginManager;
  
public FormRowSet store(Element element, FormRowSet rows, FormData formData) {
    //check the rows is not empty before store it
    if (rows != null && !rows.isEmpty()) {
        AppDefinition appDef = AppUtil.getCurrentAppDefinition();
        EnvironmentVariableDao environmentVariableDao = (EnvironmentVariableDao) AppUtil.getApplicationContext().getBean("environmentVariableDao");
        
        //Get the submitted data
        FormRow row = rows.get(0);
        
        //Add / Update each Environment Variable
        for (Object key : row.keySet()) {
            String envId = (String) key;
            String value = row.getProperty(envId);
            
            if (!envId.isEmpty()){
                EnvironmentVariable e = environmentVariableDao.loadById(envId, appDef);
                if (e != null) {
                    e.setValue(value);
                    environmentVariableDao.update(e);
                } else {
                    EnvironmentVariable e = new EnvironmentVariable();
                    e.setAppDefinition(appDef);
                    e.setId(envId);
                    e.setValue(value);
                    environmentVariableDao.add(e);
                }
            }
        }
    }
    
    return rows;
}
 
//call store method with injected variable
return store(element, rows, formData);

 

The resulted form as following.
