django - form has no errors but form.is_valid() doesn't validate

Question

I have a form that for some reason it it doesn't throw any errors (if user adds data in the text field) but form.is_valid() doesn't validate. Any ideas?

forms.py:

class MyForm(forms.Form):
    title = forms.CharField(widget=forms.TextInput(attrs={'class':'titleField')) 

mytemplate.html

  <form action="" method="post" name="form">{% csrf_token %}
  {{ form.title.errors }}
  {{ form.title }}
  <input type="submit" name='submit_button' value="Post" />
  </form>

views.py:

      if 'submit_button' in request.POST:
            form = MyForm(request.POST)
            if form.is_valid():
               cd = form.cleaned_data 
               title = cd['title']
               g = MyData(title='title')   
               g.save()

       else:
            form = MyForm() 

Solution 1

From your template, add the following:

{{ form.errors }}
{{ form.non_field_errors }}

Do you see any errors from the above?

Solution 2

You can also print (or log) error at back end too, Similarly use this:

Like, to print error:

print(form.errors)

Solution 3

I'm using this block with bootstrap

{% if form.errors %}
<div class="alert alert-danger" role="alert">
    {% for field, errors in form.errors.items %}
    {% for error in errors %}
    <b>{{ field }}</b>: {{ error }}
    {% endfor %}
    {% endfor %}
</div>
{% endif %}
