Re: Inlineformset without foreign key possible?

Thank you for pointing me in the right direction =) looks like that class 
is more generic.

Django formset for models without foreign key

2018-06-17 Thread HashRocketSyntax



I'm trying to use formset to create connections between my Neo4j nodes. 
These models have been constructed using the django-neomodel package. They 
aren't related using foreign keys, but since this *isn't* an inline formset 
that 
shouldn't matter, right?


*models.py*

class Person(DjangoNode):
  uid = UniqueIdProperty()
  name = StringProperty(max_length=50)
  created_at = DateTimeProperty(default=datetime.now)

  friends = RelationshipTo('Friend', 'FRIENDED', model=FriendRel)

  # DjangoNode class must have a Meta class and documentation specifies 
'django_node'
  class Meta:
app_label = 'django_node'

class FriendRel(DjangoRel):
  created_at = DateTimeProperty(default=datetime.now)

  class Meta:
app_label = 'django_rel'


*forms.py*

class PersonForm(forms.ModelForm):
  class Meta:
model = Person
# don't need fields for automatically assigned keys like `uid` and 
`created_at`
fields = ['name']

class FriendRelForm(forms.ModelForm):
  class Meta: 
model = FriendRel
exclude = () #"creating ModelForm without either 'fields' || 'exclude' 
attribute is prohibited"
FriendRelFormSet = formset_factory(FriendRelForm, extra=1)


*form.html*


  {% csrf_token %}
{{ form.as_p }}


  {{ friends.management_form }}

  {% for form in friends.forms %}
{% if forloop.first %}
  

  {% for field in form.visible_fields %}
{{ field.label|capfirst }}
  {% endfor %}

  
{% endif %}

  {% for field in form.visible_fields %}

  
  {% if forloop.first %}
{% for hidden in form.hidden_fields %}
  {{ hidden }}
{% endfor %}
  {% endif %}
  {{ field.errors.as_ul }}
  {{ field }}

  {% endfor %}

  {% endfor %}


  




I'm expecting a "friend" formset to appear in the rendered form, but am not 
quite sure how to get it there. If I add the following I get an error:

  class FriendRelForm(forms.ModelForm):
class Meta: 
  model = FriendRel
  exclude = ()
  fields = ['friends']
ERROR*** django.core.exceptions.FieldError: Unknown field(s) (friends) 
specified for FriendRel*

Pass value from view to non-model form

class MY_FORM(forms.Form):

  real_value = forms.CharField()
  def clean_real_value(self):
if OTHER_VALUE ...


*This throws the error:*

Re: Pass value from view to non-model form

2018-06-23 Thread HashRocketSyntax

It seems to like that! `(arg1, OTHER_VAL=OTHER_VAL) 

Now I'm trying to access that other_value:
  def __init__(self, *args, **kwargs): 
OTHER_VAL = kwargs.get('OTHER_VAL') #tried these:  #kwargs['OTHER_VAL'] 
#kwargs.pop('OTHER_VAL')
super(MY_FORM, self).__init__(*args, **kwargs)


Keep on getting errors like:
`KeyError: 'OTHER_VAL'`

# or 
__init__() got an unexpected keyword argument 'OTHER_VAL'

Clean ValidationError not showing when form.is_valid() called

2018-06-23 Thread HashRocketSyntax



I'm trying to show my ValidationError from clean_MY_VALUE in the template.


*template*

{% csrf_token %}
  {{form.as_p}}
  Submit
{{ form.errors }}
{{ form.non_field_errors }}


*views.py*

def MY_VIEW_CLASS(request, MY_ARG):

  if request.method=='POST':
form = MY_FORM(request.POST)

if form.is_valid():
  MY_VALUE = form.cleaned_data['MY_VALUE']
  # do more stuff

required = True,
max_length = 70,

  def __init__(self, *args, **kwargs): 
self.MY_ARG = kwargs.pop('MY_ARG', None)

MY_ARG = self.MY_ARG

if MY_VALUE and MY_ARG == True:
  raise ValidationError("this is the error message.")

if any(self.errors):
return self.errors

# return the cleaned data
return data

What's weird is that when I debug, I cannot see the ValidationError I just 
created in errors.

(Pdb) raise forms.ValidationError("That is causing an error.")*** 
django.core.exceptions.ValidationError: ['That is causing an error.']

Django how to go about using npm modules with static/ templates

2018-07-13 Thread HashRocketSyntax



I have recently added *npm* to my project in order to keep better track of 
my js dependencies. Previously I have just been git cloning to my 
static/vendor folder.

I've also added *gulp* , but have only got it doing hello world things 
right now. It seems simple enough - it can watch files, minify assets, 
compile Sass. Eventually I will probably switch to *Webpack*, but gulp is 
simple and working for now. I don't want to use *django-compressor* or 
*django-pipeline*.

--

So let's say I run npm install vis to pull in visjs. It gets added to 
node_modulesand a record is added to package.json dependencies.


*A)* Do I reference vis/dist right where it is in node_mods in my template 
scripts?
