    <p>I have a settings page which has two forms for handling the settings for two different Models. The Profile model form works. The Chef model form doesn't. The form fails gracefully, and isn't throwing a Django error page - so in using pdb, I found the form is not valid, and is throwing a Syntax Error.</p> <p>I'm confused as to which field this error is coming form. Any help would be greatly appreciated. Thanks!</p> <p><strong>Error:</strong></p> <pre><code>*** SyntaxError: SyntaxError('unexpected EOF while parsing', ('&lt;string&gt;', 0, 0, '')) </code></pre> <p><strong>HTML</strong> </p> <pre><code> {% if form.is_multipart %} &lt;form enctype="multipart/form-data" method="post" action="."&gt;{% csrf_token %} {% else %} &lt;h3&gt;Profile Settings&lt;/h3&gt; &lt;form method="post" action="."&gt; {% endif %} &lt;dl&gt; &lt;dt&gt;{{form.photo.label}}&lt;/dt&gt; &lt;dd&gt;{{form.photo}}&lt;/dd&gt; &lt;dt&gt;{{form.firstname.label}}&lt;/dt&gt; &lt;dd&gt;{{form.firstname}}&lt;/dd&gt; &lt;dt&gt;{{form.lastinitial.label}}&lt;/dt&gt; &lt;dd&gt;{{form.lastinitial}}&lt;/dd&gt; &lt;/dl&gt; &lt;button type="submit"&gt;Save&lt;/button&gt; &lt;/form&gt; &lt;h3&gt;Chef Settings&lt;/h3&gt; &lt;form action="{% url edit_chef chef.id %}" method="post" accept-charset="utf-8"&gt;{% csrf_token %} &lt;dl&gt; &lt;dt&gt;{{chefform.category.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.category}}&lt;/dd&gt; &lt;dt&gt;{{chefform.price.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.price}}&lt;/dd&gt; &lt;dt&gt;{{chefform.meal.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.meal}}&lt;/dd&gt; &lt;dt&gt;{{chefform.language.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.language}}&lt;/dd&gt; &lt;dt&gt;{{chefform.address.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.address}}&lt;/dd&gt; &lt;dt&gt;{{chefform.neighborhood.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.neighborhood}}&lt;/dd&gt; &lt;dt&gt;{{chefform.city.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.city}}&lt;/dd&gt; &lt;dt&gt;{{chefform.state.label}}&lt;/dt&gt; &lt;dd&gt;{{chefform.state}}&lt;/dd&gt; &lt;dt&gt;{{chefform.menu.label}}&lt;span id="rBann" class="minitext"&gt;1000&lt;/span&gt;&lt;/dt&gt; &lt;dd&gt;{{chefform.menu}}&lt;/dd&gt; &lt;/dl&gt; &lt;button type="submit"&gt;Save&lt;/button&gt; &lt;/form&gt; </code></pre> <p><strong>Chef Form</strong></p> <pre><code>class ChefForm(forms.ModelForm): class Meta: model = Chef fields = ('category','meal','price','language','address','neighborhood','city','state', 'country', 'menu') category = forms.ChoiceField( label=_("Food style"), choices=([('Afghan','Afghan'),('African','African'),('American','American'),]), required=True) meal = forms.ModelMultipleChoiceField( label=_("What is your best meal?"), queryset=Meal.objects.all(), required=True) price = forms.IntegerField( label=_("Price per person"), widget=forms.TextInput(), required=True) language = forms.ModelMultipleChoiceField( label=_("Languages spoken"), queryset=Language.objects.all(), required=True) address = forms.CharField( label=_("Your Address"), widget=forms.TextInput(), required=True) neighborhood = forms.CharField( label=_("Your Neighborhood"), widget=forms.TextInput(), required=True) city = forms.CharField( label=_("Your City"), widget=forms.TextInput(), required=True) state = forms.CharField( label=_("Your state"), widget=forms.TextInput(), required=True) country = forms.CharField( label=_("Your country"), widget=forms.TextInput(), required=True) menu = forms.CharField( label=_("What's unique about your cooking &amp; home?

    1. COWhat exactly are you typing into PDB to get this error? For example you can create that error if you run a pdb print command with no arguments..

    3. COWhy are you getting all the attributes manually from the modelform `cleaned_data`? The whole point of a modelform is you can just do `chefform.save` and get a ready-saved model instance based on your form.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
