    <p>I have a template which allows user to enter search parameter (search.html)</p> <pre><code>{% from "_formhelpers.html" import render_field %} &lt;form method=”post”&gt; &lt;dl&gt; {{ render_field(form. notificationId) }} {{ render_field(form. recordName) }} &lt;/dl&gt; &lt;div id="searchResults" &gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p>Macro</p> <pre><code>{% macro render_field(field) %} &lt;dt&gt;{{ field.label }} &lt;dd&gt;{{ field(**kwargs)|safe }} {% if field.errors %} &lt;ul class=errors&gt; {% for error in field.errors %} &lt;li&gt;{{ error }}&lt;/li&gt; {% endfor %} &lt;/ul&gt; {% endif %} &lt;/dd&gt; {% endmacro %} </code></pre> <p>And a template for search results(result.html)</p> <pre><code>{% for notification in content %} Result: content[notification]['type'] }}&lt;/td&gt; {% endfor %} </code></pre> <p>I am using the following ajax request to get search results and display in the above template.The ajax function is called on keyup of both the search fields</p> <pre><code>$.ajax( { url: ‘result’, dataType: "html", data:createQueryString(),// gets the value from the dataFields and creates a queryString success: function(data) { $("# searchResults").html(data); } }); </code></pre> <p>I also I have 2 views one for the searchcriteria section( the section containing the 2 search fields) and one for the search results section.</p> <pre><code>class NotificationSearchView(MethodView): def get(self): searchform = SearchForm() return render_template("search.html”, searchform=searchform) @classmethod def registerSelf(cls, app): NotificationSearchView.app = app app.flaskApp.add_url_rule('/search ', view_func=NotificationSearchView.as_view(‘search’)) class NotificationResultView(MethodView): def get(self): searchform = SearchForm() success, content=self.performSearch(searchform) //search method which takes the search parameters and performs the search return render_template("result.html”, content=content) @classmethod def registerSelf(cls, app): NotificationResultView.app = app app.flaskApp.add_url_rule('/result', view_func= NotificationResultView.as_view(‘result’)) </code></pre> <p>WTF form class</p> <pre><code>from wtforms import Form, TextField class SearchForm(BaseForm): notificationId = TextField(notificationId) recordName = TextField(recordName) </code></pre> <p>The issue which I am facing is that the wtf form object isn’t populated when the ajax call is made to the NotificationResultView, which I believe is because there is no post request fired, but according to my design there is no need of a post request.</p> <p>I have tried by making the ajax request as post request but even then the wtf form object comes back empty.</p> <p>Now my only other option is if I pass the search criteria in the query string when making the ajax call, but not sure if that’s the best approach.Please suggest how to proceed in this case. </p>

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.
