I'm trying to create simple ExtJs application that manages Users and User's Roles. Set of REST services provide this functionality on back end. When I assign a new Role to a User, appropriate data store sends POST (create) requests to the service. However when I remove existing Role from a User, it's removed only from store locally without sending DELETE request to the service. Here is my code: Model: <pre><code>Ext.define('UserRole', { extend: 'Ext.data.Model', fields: [ { name: 'Id', mapping: "Id" }, { name: 'RoleId', mapping: "RoleId" }, { name: 'UserId', mapping: "UserId" } ] }); </code></pre> Store With proxy: <pre><code>Ext.define('UserRoleStore', { extend: 'Ext.data.Store', model: 'UserRole', autoload: false, proxy: { type: 'ajax', reader: { type: 'json', root: 'd.results' }, api: { read: '/accessmanager.svc/Users(\'{userid}\')/Roles?$format=json', create: '/accessmanager.svc/UserRoles?$format=json', update: '/accessmanager.svc/UserRoles?$format=json', destroy: '/accessmanager.svc/UserRoles?$format=json' }, updateApiUrlWithUserId: function (userId) { this.api.read = this.api.read.replace('{userid}', userId); } } }); </code></pre> Method that based on selected checkboxes updates the UserRole store <pre><code> var chekboxes = Ext.ComponentQuery.query('userdetails #roleslist')[0]; var selectedUserId = this.selectedUserId; var selectedUserRoleStore = this.selectedUserRoleStore; Ext.each(chekboxes.items.items, function (cb) { var exists = false; Ext.each(selectedUserRoleStore.data.items, function (cs) { if (cs.data.RoleId === cb.inputValue) { exists = true; } }); if (cb.getValue() && !exists) { var newRole = Ext.create('UserRole', { RoleId: cb.inputValue, UserId: selectedUserId }); selectedUserRoleStore.add(newRole); } else if (exists && !cb.getValue()) { // delete existing role var record = selectedUserRoleStore.findRecord("RoleId", cb.inputValue); selectedUserRoleStore.remove(record); } }); selectedUserRoleStore.sync(); </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
