  1. PODjango csv error and best place to write business logic
    text
    copied!<p><strong>EDIT:</strong></p> <p>Q1 is solved by adding <code>enctype="multipart/form-data"</code> to the form template. Please comment on Q2.</p> <p><strong>Qn1:</strong> I get the below error when try to read a csv file, which is uploaded through Forms. Exception may be at this line.</p> <pre><code>records = csv.reader(f) </code></pre> <p>Not sure what to pass . Please see the code below.</p> <p><strong>Qn2:</strong> Is it ok to do the csv processing in the model (the csv is for uploading domain data, hence validate/and persist as domain objects). I am new to Django/Python, and most of the example I see so far has not much method in models. This is bit different from what I used to where you capture all the business logic associated with the model in it. Wonder the idiomatic usage in django.</p> <h2>Exception:</h2> <pre><code>Django Version: 1.4.1 Exception Type: TypeError Exception Value: argument 1 must be an iterator </code></pre> <h2>View:</h2> <pre><code>def upload(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): w = Testme() w.importCsv(form.cleaned_data["file"]) return HttpResponseRedirect('/') else: form = UploadFileForm() return render_to_response('setup.html', {'form': form},context_instance=RequestContext(request)) </code></pre> <h2>Form:</h2> <pre><code>class UploadFileForm(forms.Form): title = forms.CharField(required=False) file = forms.FileField(required=False) </code></pre> <h2>Model:</h2> <pre><code>class Testme(models.Model): code = models.IntegerField() ctu = models.IntegerField() address = UsAddress def importCsv(self, f): records = csv.reader(f) for line in records: logger.debug(line) </code></pre>
