    <p>I have a select tag in my html file. i want when user change his/her selection, my page which have to work with ajax, sends the value of user selection to my views.py function and then i recreate the page with this value. my html code:</p> <pre><code>&lt;div id="response&gt; &lt;select name="page_length_name" id="page_length_id"&gt; &lt;option id="opt1"&gt;10&lt;/option&gt; &lt;option id="opt2"&gt;20&lt;/option&gt; &lt;option id="opt3"&gt;30&lt;/option&gt; &lt;option id="opt4"&gt;40&lt;/option&gt; &lt;/select&gt; //here is a table &lt;/div&gt; </code></pre> <p>(this select tag isn't in form). i want it to be fixed untill user change data. so i think i have to use cookie. i don't know can i use function like this, although select isn't in form? Should it be "POST" method? can post only be used in forms? if yes, so how can i send data(my select tag) to server?</p> <pre><code>$(function() { $('#page_length_id').change(function() { temp = ["page_length_id"].options[selectedIndex].value; $.ajax({ type: "POST", data: temp, url: 'backup/', success: function(data) { alert("success"); $("#response").html(data); } }); }) </code></pre> <p>and also how can i force this select value to be in cookie? is it enough to do it by only this line of code in views.py?:</p> <pre><code>table_length = request.COOKIES.get('table_length') </code></pre> <p>here is my viwes.py:</p> <pre><code>def backup(request): if request.is_ajax(): try: table_length = request.COOKIES.get('table_length') except Exception: table_length = 10 if not page_length: table_length = 10 //here i create the page with xsl and send it to a page to be shown result = style.applyStylesheet(doc) out = style.saveResultToString( result ) ok = mark_safe(out) style.freeStylesheet() doc.freeDoc() result.freeDoc() if request.method == 'POST': return HttpResponse(ok) else: return render_to_response("show.html", { 'str': ok, }, context_instance=RequestContext(request)) </code></pre> <p>thank you.</p>

    1. COToo many question. Please, specify a problem you have. Does your approach raise errors? Also, did you set your ajax-request correctly with csrf: [docs](https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax)

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.
