copied!<p>Several things are not good here...</p> <p>1) The recommended thing after a POST is to redirect. This avoids the infamous popup saying that you are resubmitting the form when using the back button.</p> <p>2) You don't need to say <code>if request.method == 'POST'</code>, just <code>if request.POST</code>. That makes your code easier to read.</p> <p>3) The view generally looks something like:</p> <pre><code>def myview(request): # Some set up operations if request.POST: form=MyForm(request.POST) if form.is_valid(): # some other operations and model save if any # redirect to results page form=MyForm() #render your form template </code></pre> <p>That is not to say that there can't be much simpler and much more complicated views. But that is the gist of a view: if request is post process the form and redirect; if request is get render the form.</p> <p><strike>I don't know why you are getting an unicode error. I can only think that it is related to one of your models that you don't provide.</strike> The error, as spookylukey mentions is in his comment, most likely is caused by you submitting a string instead of a dict to the initial parameter.</p> <p>I really recommend the django documentation, in <a href="http://docs.djangoproject.com/en/dev/intro/tutorial01/#intro-tutorial01" rel="noreferrer">particular the tutorial.</a>, but there is also the very nice <a href="http://www.djangobook.com/en/2.0/" rel="noreferrer">Django Book</a>.</p> <p>All that said, I think you want something like:</p> <pre><code>def search(request, q=None): if request.POST: form = SearchForm(request.POST) if form.is_valid(): q = form.cleaned_data['q'] url=reverse('search_results', args=(q,)) return HttpResponseRedirect(url) if q is None: form = SearchForm() else: form = SearchForm(initial={'q': q}) return render_to_response('things/search.html', { 'form': form, }) </code></pre> <p>Notice that the parameter to initial is a dict of the field values of your form.</p> <p>Hope that helps. </p>
