Re: passing django models data to python script

so far, I know how to:
build a REST API with django,
get user input using reactjs,
make post and get request to get data from the API or update the API 
data from user input,
However, I do not know how to access the models values in my python 
script, run the python script with django, and update the API with so 
that it contains the output in order for me to be able fetch the 
output with react.


I am not sure if im doing this the easiest way, as it sounds so 
complicated, but I am open to suggestions on better ways of doing this.


I would probably take my python script and convert it into one or more 
model methods. In principle, if the data needs to be manipulated the 
model should do the heavy lifting. It can be argued that database 
procedures should do it but that is a rare art and the Django ORM (and 
model methods) make it much easier to maintain.


At some point it needs to be saved to the database so the broad idea is 
to put the user input into a model field then override the model's 
save() method to call model methods to do the manipulation and perhaps 
fill up some other fields before or add child records after the save 
actually happens.


My typical pattern for such a save is ...

    def save(self, *args, **kwargs):
    # need to pass links across the super boundary
    links = self.make_useful_links()
    super(Substance, self).save(*args, **kwargs)
    self.create_child_records(links)

... where Substance is the model name and 'links' is returned from a 
model method. The call to super() triggers the normal Substance.save() 
method. Because child records need the substance id for their FK, they 
cannot be created until after the actual save() beyond which we can 
guarantee the substance.id is not None.


There are also pre_save and post_save signals available but I prefer the 
above because I find it easier to see what the code is doing.


Your question about how to access the model values in your script is 
solved if you embed the script in a model method. Every model method 
should have 'self' as the first arg. 'self' is the model instance so 
every field is available via self.field. For example if the Substance 
name is used to generate a bunch of URLs pointing to a bunch of public 
databases containing information on that substance ...


    def make_useful_links(self):
        links = list()
    for database in databases:
            links.append(self.assemble_url())
            # self.assemble_url() has access to self.name and 
self.cas_no fields

    return links

As it happens this could be done after the super() call but if you want 
to save anything on the model, those fields have to be complete before 
the save()

Django ForeignKey field name “check” raises SystemCheckError

[Eric Palmitesta]

The Django docs 
(https://docs.djangoproject.com/en/1.11/topics/db/models/#field-name-restrictions)
 
state there are only two restrictions on model field names:


   1. A field name cannot be a Python reserved word
   2. A field name cannot contain more than one underscore in a row


However, given the following example, it doesn't look like I can use the 
field name `check` as a ForeignKey.

class Check(models.Model):


name = models.CharField(max_length=100)


class MyModel(models.Model):


# this works fine
#check = models.BooleanField()

# this breaks
check = models.ForeignKey(Check, on_delete=models.PROTECT, 
related_name='+')

Here's the error:

$ python manage.py check
SystemCheckError: System check identified some issues:


ERRORS:
myapp.MyModel: (models.E020) The 'MyModel.check()' class method is 
currently overridden by 


Are the docs wrong, or am I doing something wrong?

Question on implementing a Django auction site

[beneficialmusic]

I'm relatively new to Django and have been learning with a long term 
interest in developing an auction site. I can't seem to find any up to date 
existing auction projects available for reference. There are some on Git 
Hub, but most are outdated or not very developed.

My question is: since my auction site would need a lot of functionality 
used in a typical e-commerce site (shopping cart, payments, shipping 
details, etc), would it be best to start from an existing open source 
e-commerce project and modify that for auction purposes, and if so, which 
would you recommend (Django Shop, Shuup, Satchless, something else)?

Re: How to create model for this json data

['Amitesh Sahay' via Django users]

Hi,
First, try to understand the error messages. It says there are fields that are 
required, but you are leaving them blank. Then, there are some fields those 
cannot have "null", but soemhow you are adding null values to them.
I would suggest using below Django CLI commands to add the data to your table
python manage.py loaddata .
Below is the link that will guide you with further informationDjango dumpdata 
and loaddata (Example)
