I'm trying to add a new Goal via POST using my select option populated by the Referenced Category. The dropdown populates correctly, but the key I'm getting from the value returned is causing a ReferenceProperty Error.
models.py:
class Categories(db.Model):
name = db.StringProperty(required=True)
amount = db.FloatProperty(required=True)
class Goals(db.Model):
name = db.StringProperty(required=True)
amount = db.FloatProperty(required=True)
category = db.ReferenceProperty(Categories)
add_goal.html:
select type="select" name="category" id="id_cat"
{% for c in cats %}
option value='{{c.name}}' {{ c.name }} /option
{% endfor %}
/select>
CORRECTED VERSION:
{% for c in cats %}
{{ c.name }}
{% endfor %}
views.py:
def post(self):
cat_key = db.Key.from_path('Categories', self.request.get('category'))
logging.info('cat_key= '+ str(cat_key))
g = Goals(name=self.request.get('name'),
category=cat_key,
amount=float(self.request.get('amount')))
g.put()
return webapp2.redirect('/view_goals')
CORRECTED VERSION:
def post(self):
cat_key = db.Key.from_path('Categories', int(self.request.get('category')))
g = Goals(name=self.request.get('name'),
category=cat_key,
amount=float(self.request.get('amount')))
g.put()

I'm stuck with the issue that I need to insert the list [ ] in the model field while using SQLite,
Group_Model.py:
class ClassificationGroup(models.Model):
vendor_id = models.ForeignKey(Vendor, on_delete=models.CASCADE, default=None, null=True)
id = models.IntegerField(primary_key=True)
name = models.CharField(max_length=100)
description = models.CharField(max_length=1000)
classification_id = models. [what do i take here to make it capable to store list of ids that will be related to the classification table.]
Classification_Model.py
class Classification(models.Model):
id = models.IntegerField()
name = models.CharField(max_length=100)
description = models. CharField(max_length=1000)
domain_name = models.CharField(max_length=200)
i just want to store the list of classification in the one field of the Classification Group Mentioned above, Please help me out in this.
Add a method to your class to convert it automatically.
import json
class ClassificationGroup(models.Model):
#...
classification_id = models.CharField(max_length=200)
def set_classification_id (self, lst):
self.classification_id = json.dumps(lst)
def get_classification_id (self):
return json.loads(self.classification_id)
your view:
obj = ClassificationGroup.objects.create(name="name",**data)
obj.set_classification_id([1,2,3])
obj.save()
#there are several examples of using this method
your HTML:
{% for obj in objects %}
{{ obj.name }}
{{ obj.get_classification_id }}
{% endfor %}
my question seems tricky to me, but i'm certain someone could derive a solution to it. i've a boolean field, but i want to add a functionality in which when the boolean is been clicked (True), i could implement an {% if %} and {% else %} which could be, add a particular amount to the original amount, if the boolean field is True. my code is below for proper understanding...

I am looking for a in_array function equivalency in volt.
Is there another way to do this?
{% for modelObj in modelList %}
{% if modelObj.getId() in modelIdCheckedList %}
{{ check_field('id[]', 'value':modelObj.id, 'checked': true) }}
{% else %}
{{ check_field('id[]', 'value':modelObj.id, 'checked': null) }}
{% endif %}
{% endfor %}
I need to do something like this
{{ check_field('id[]', 'value':modelObj.id, 'checked': in_array(modelObj.getId(), modelIdCheckedList )) }}
Could you help me?
There are two ways you can achieve this.
Using a Function
Register the in_array as a function that Volt will understand. In your Volt registration you need to add the function to the compiler as follows:
$volt = new Phalcon\Mvc\View\Engine\Volt($view, $diContainer);
$volt->setOptions( .... );
$volt->getCompiler()->addFunction(
'in_array',
function ($parameters) {
return 'in_array(' . $parameters . ')';
}
);
Using an Extension
You can also register a PHP function extension, which will allow all PHP functions to work in Volt.
Create your extension class
class PhpFunctionExtension
{
/**
* This method is called on any attempt to compile a function call
*/
public function compileFunction($name, $arguments)
{
if (function_exists($name)) {
return $name . "(". $arguments . ")";
}
}
}
Register it in the Volt compiler
$volt = new Phalcon\Mvc\View\Engine\Volt($view, $diContainer);
$volt->setOptions( .... );
$volt->getCompiler()->addExtension(new PhpFunctionExtension());
https://docs.phalconphp.com/en/latest/reference/volt.html#extending-volt
https://docs.phalconphp.com/en/latest/reference/volt.html#extensions
Use the in operator:
{{ modelObj.getId() in modelIdCheckedList }}
So you may do something like:
{{ check_field('id[]', 'value': modelObj.id, 'checked': modelObj.getId() in modelIdCheckedList }}

I have product with image but when i try show image only this product django show me all image product how i can fix it ? I try wite slice don't work beacuse if i do |slice:"0:1" show me image but not image this product.

My views.py
def product_detail(request, id, slug):
product = get_object_or_404(Product,
id=id,
slug=slug,
available=True)
products = Product.objects.all()
return render(request,
'shop/product/detail.html',
{'product': product,
'products': products})
and my detail.html
{% extends "shop/base.html" %}
{% load static %}
{% block title %}{{ product.name }}{% endblock %}
{% block content %}
{% for p in products %}
<img src="{{p.detail_url}}" class="img-responsive">
{% endfor %}
</div>
</div>
{% endblock %}
if u want somethink more comment and i will how fast i can add it .
change your view
def product_detail(request, id, slug):
product = get_object_or_404(Product,
id=id,
slug=slug,
available=True)
return render(request,
'shop/product/detail.html',
{'product': product})
and in template change
{% for p in products %}
to
{% for p in product %}
you can solve the problem by removing one 's' in template but i suggest change the view function as mentioned
in case your using Pillow not just the address of image as string change this
{{p.detail_url}}
to
{{p.fieldname.url}}
I am new to shopify but upon my research... this code should work.
{% assign dcor = "decor, decors, Decor, Decors" | split: ", "%}
{% assign dcors = "décor, décors, Décor, Décors" | split: ", "%}
{{ product.title | replace: 'dcor', 'dcors' }}
But no luck at all.
Nope. Won't work. You can't match/replace elements from arrays. You have to manually replace each variation
{% assign dcor = "decor, decors, Decor, Decors" | split: ", "%}
{% assign dcors = "décor, décors, Décor, Décors" | split: ", "%}
{% assign d = dcor.size | minus: 1 %}
{% for i in (0..d) %}
{% assign title = product.title | replace: dcor[i],dcors[i] %}
{% endfor %}
{{ title }}
