django - TemplateSyntaxError caught DoesNotExist while iterating through a forloop on a populated list of forms -

-

I am following this useful article. Unfortunately, that does not indicate the template code, so I'm guessing there.

I want to add several types of formats to a single model in one page, with some common property set, in either form or in the variables of the page or at the top of the page. This is for a teacher's market.

My thoughts: 

  def record_assessments (request, teaching group, purpose): theclass = TeachingGroup.objects.get (name__iexact = teachinggroup)) students = pupil.objects. Filter (teaching_group = theclass) theobjective = Objective.objects.get (code = objective) thedate = datetime.date.today () if request.method == 'POST': aforms = [PupilAssessmentForm (POOT request, prefix = xid , Instant = Assessment ()) For students in X if all (for F.I.I.VIDID) (for AFFF): For F.Formes: new_record = af.save (commit = False) new_record .objective = theobjectiv E new_record.date = thedate new_record.save () Redirection redirect ("/ app /" + theclass + "/" + marksheet + "/" + theobjective.strand.code | bottom + "/") Other: forms = [PupilAssessmentForm (Prefix = str (x.id)) for students in x Return] render_to_response ('recordassessments.html', local ())   
 I have not managed to check if the loop In logic, as I have not managed to properly post the form so far  
 If I put  
  else: aforms = [PupilAssessmentForm (prefix = str (x.id), instance = x) then the page presents properly. ]   
 But then I'm building model models with model models for an object in the student model, which seems wrong.  
 My Template:  
  {% in format for%} & lt; Form action = "method =" post "& gt; {{Af.instance}} {{af.errors}} & lt; P & gt; {{Eff}} {% endfor%} & lt; Input type = "submit" value = "submit" & gt; & Lt; / Form & gt; Error (selected snippet):  
  Exception type: TemplateSyntaxError Exception value: caught NotNotExist while rendering: Error on line 20 Caught Do NotExist while rendering: 20% {% for aforms%} in <% code >   
 and yet the list of forms appears in the Page Variable:  
  aforms [& lt; Two.app.forms 0x21db050 & gt; 0x21db650 & gt;] on    
 
 0x21db0d0 at & amp; Gt; And & lt; Pup.AssificationForm object; 
 Strange, Django Dieses do not throw away the Noxxist while presenting the models ... But .... you are providing a form. I suggest that you have to do some investigation for the result in your idea code You can be sure that you are getting results in students and your other questions.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.
