kandi X-RAY | placeholder Summary
A placeholder uses operator overloading to create partially bound functions on-the-fly. When used in a binary expression, it will return a callable object with the other argument bound. It's useful for replacing lambda in functional programming, and resembles Scala's placeholders.

QUESTION
I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings

The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

I'm trying for a long time to get my labels on the left side on my input fields. I'm banging my head against the wall. I use a font-awesome icon in the label.
I tried a lot of searches on Google and Stack Overflow and tried stuff like inline-block which I see should work but it didn't work for me. My code so far. I guess it's an easy fix for all the great people that are here.
...ANSWER
Answered 2021-Apr-13 at 19:11The easiest method, in my opinion, is to turn .wrapperSnippet into a CSS Grid layout.
Grid is supported by all modern browsers but IE supports an older version of the spec.
We can define the grid with two columns: one of width auto, and the other with 1fr. auto means that it will take up as much space as needed to fit the element, then the 1fr will fill the remaining space.

Hello my favorite people!
I am trying to send an email after submitting a form, with the AUTO INCREMENT number attached to the email because the AUTO INCREMENT number is the clients Job Card Reference Number. So far i have successfully created the insert script which inserts the data into the database perfectly, and also sends the email too. But does not attach the AUTO INCREMENT number into the email. The INT(11) AUTO INCREMENT primary key is "job_number" in my MySQL database.

QUESTION
I'm trying to put a text before and after the Var content. Unfortunately I was able to put the text only after. I'm a fan, so I don't know Js very well.
I hope to find a solution here, further info below.
My content currently looks like this: 0.000 Kcal (this is an html placeholder)
When the function is executed, the content looks like this: x.xxx Kcal (this is the result of the function + text after var)
What I'm trying to do should be like this: BMR x.xxx Kcal (so add some text before the numbers, but it is not html)
Below is the code.

QUESTION
i am trying to make login function but the function always make my input was wrong even i using the correct data from database
here's my login section
...ANSWER
Answered 2021-Jun-15 at 11:46From your image, it shows that the password (firsttt) is in the database in plaintext. However, when you are querying it, you are using md5 to hash it before you check the database. The MD5 hash of firsttt is 568745cb18115e238907fbf360beb37a and since that doesn't match the field in the database it does not return a result. If you want to see the result return positive, you can remove the md5() function for now just to see it but you should secure the database in some other way.
MD5 alone would not be secure as common passwords are easily detected. The passwords need to be hashed and salted, which makes them more unique and unindentifiable.
For example, php provides a password_hash function that will hash and salt the password: https://www.php.net/manual/en/function.password-hash.php
which you should use when adding a user to the database.
They also provide a password_verify function that will be able to tell you if the submitted password is correct: https://www.php.net/manual/en/function.password-verify.php

Answered 2021-Jun-15 at 12:14Whenever actionmodal is open you can save the index() of div which has open that modal inside data-attribute . Then , when appendaction button is clicked get the data-attribute and then use $(".steplist .input-group:eq(" + row_no + ")").. to add new data inside your input-group div.

You can use placeholder like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
