Hi, Can anyone help me with something. I want to add a button in a form ( in django admin page ) which redirect the user to another page loaded from static template, and after user select something from that page it should redirect back to the original django admin form to complete the rest of the form. Is there any way to do this ?

use urls

use urls

Is there any other way.. because the url changes to situation like 'add' or 'change'. So....

study a bit of database theory before Django

hi fellas, i have a wallet field which uses a DecimalField for storing btc value wallet = models.DecimalField(decimal_places=8, max_digits=8, blank=True, null=True, default=0) I just realized that when the wallet's value becomes 1.xxxxxx it throws an error

Good to use CharField in case of DecimalField

Here

since its for financial stuff that's why i decided to use DecimalField

```Traceback (most recent call last): File "/usr/lib/python3.6/code.py", line 91, in runcode exec(code, self.locals) File "<console>", line 1, in <module> File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/models/query.py", line 752, in update rows = query.get_compiler(self.db).execute_sql(CURSOR) File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/models/sql/compiler.py", line 1492, in execute_sql cursor = super().execute_sql(result_type) File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/models/sql/compiler.py", line 1131, in execute_sql sql, params = self.as_sql() File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/models/sql/compiler.py", line 1458, in as_sql val = field.get_db_prep_save(val, connection=self.connection) File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/models/fields/__init__.py", line 1510, in get_db_prep_save return connection.ops.adapt_decimalfield_value(self.to_python(value), self.max_digits, self.decimal_places) File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/backends/base/operations.py", line 517, in adapt_decimalfield_value return utils.format_number(value, max_digits, decimal_places) File "/home/mcroni/mybitstoreenv/lib/python3.6/site-packages/django/db/backends/utils.py", line 238, in format_number value = value.quantize(decimal.Decimal(1).scaleb(-decimal_places), context=context) decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>] ```

So here you are trying to post a char value in decimal field

even if i post a DecimalField it throws the same error

Profile.objects.filter(username="don").update(wallet=Decimal(1.00000000))

Profile.objects.filter(username="don").update(wallet=Decimal(1.00000000))

max digits 8 and decimal place 8 but you have more than eight digits in this example

even making it a 7 digits causes the same issues

try to give only Decimal(1)

once the figure starts with 1 it will throw the error

try to give only Decimal(1)

same

even making it a 7 digits causes the same issues

have u tried with Decimal("1.000") ?

Change the max_digits

Here

have u tried with Decimal("1.000") ?

yeah

Change the max_digits

to what please, bitcoin's conventional decimal places are 8

yeah

the same ?

the same ?

yes please

to what please, bitcoin's conventional decimal places are 8

Remove max_digits and try once

wallet = models.DecimalField(decimal_places=8, blank=True, null=True, default=0)

wallet = models.DecimalField(decimal_places=8, max_digits=25, blank=True, null=True, default=0)

Or try this

btw when i try to update using the admin i get this error Ensure that there are no more than 0 digits before the decimal point.

btw when i try to update using the admin i get this error Ensure that there are no more than 0 digits before the decimal point.

which is the value that causes the error ?

anything that begins with 1

anything that begins with 1

even just 1 ?

lol yeah please

lol yeah please

The mantissa must fit in the max_digits; The decimal places should be less than decimal_places; And according to the DecimalValidator : the number of whole digits should not be greater than max_digits - decimal_places; the 3 rules are these ones

so if i what to have something like 1.xxxxxxxx to 8 decimal places and also support 0.xxxxxxxx to 8 decimal places can u suggest what i should use

eg. models.DecimalField(decimal_places=x,max_digits=x) ?

eg. models.DecimalField(decimal_places=x,max_digits=x) ?

so if BTC has max decimal places to 8 you should set at least 9 as decimal places

ok

and maintain the max_digits at 8?

Please help I deployed my website in a shared hosting but : 1) Site is rendering only two or three static images in the webpage rest of the images aren't rendered (all static images are in same directory) 2) To solve the problem I destroy the python app and redeployed with same steps but now the even the css and js files aren't rendering 3) Not only that django's inbuilt admin panel is also not rendering with default css

so if BTC has max decimal places to 8 you should set at least 9 as decimal places

cc.Profile.wallet: (fields.E134) 'max_digits' must be greater or equal to 'decimal_places'.

cc.Profile.wallet: (fields.E134) 'max_digits' must be greater or equal to 'decimal_places'.

yup so >= 9

What is the reason behind it? You have to call decimal conversion before any calculations and for storing back to database you have to convert to string. Please share your knowledge. Thank you.

models.DecimalField(max_digits=16, decimal_places=8, default=Decimal(0))

solved thanks

sorry - I didn't read the second part of your message I can only add that it is quite bold to meddle in such complex topics for a beginner

Please help me 🙏🙏🙏

Maybe anyone is here, yes, but they are not obliged to read everyone's message here neither to reply to everyone's message, if someone wants to reply to your message, they will do that, just don't try to draw attention to your message writing "anyone?" every 5 minutes, that will lead you to be warned for SPAM/Flood, just be patient or use Google/DuckDuckGo to research about your question instead of wasting time here waiting for people to do your work. Have a nice day 😊

if you know what it is, then apparently you saw it in the documentation - there are usually examples

it just simply says override authenticate()

it just simply says override authenticate()

first you need to decide how to act - there are many options your main problem is that no one except you can do it right so you will have to at least superficially familiarize yourself with all the possibilities, then decide what is supposedly more suitable - but do not rush - this will not necessarily be the final decision - perhaps in trying to implement it you will understand that it is actually not very suitable it's a hard path, but most likely you will have to go through it
