QUESTION
I have developed a Python package. My structure is the following :
...ANSWER
Answered 2021-May-26 at 13:52User configuration should usually be kept in the os-specific locations for application configs. The usual way to handle it as a package author is to
- write a default config file and put it into the package, e.g. at
src/my_package/default.ini
- this is better than writing the config as code, as yourmain.py
probably does, because you can re-use your parsing step, can copy the default config to get a valid user config, and just have to maintain a single file type - copy the default config into a user-specific directory, use
appdirs
to find out which one is correct on each os- you can either ask your users if it's ok to create a new config at e.g.
/home/user/.configs/my_app
and do it after confirmation, or just do it and tell them where to find it in case they want to customize something
- you can either ask your users if it's ok to create a new config at e.g.
- on application start, parse the default config first, then parse the user config and overwrite differing settings
- if you also allow configuration via environment variables, those will be parsed afterwards and should overwrite both default- and user-config
Just to have a starting point, my config-parsing usually looks somewhat like this:
config.py, somewhere in your package
QUESTION
We run a site with WordPress and use a template for our design.
On our homepage we have a scroll of our blog posts that includes a title, author/post info, reading time and an "excerpt"?
We're trying to get rid of the "excerpt"
blog-post-content-list-sider
is the div and the text is just a #text within.
Everything I've looked up is something like .blog-post-content-list-sider { display: none; }
but that would hide the entire thing not just one aspect of it (if I understand correctly)
This is the code for 1 blog-post-content-list-sider
The part that starts with "A Cutting-Edge" is the text that I need removed from each post on our page.

QUESTION
I am following a tutorial to send and receive data from my server in an Ionic application and I am having trouble doing that because of CORS. I am very familiar with the CORS issue and have used the "Access-Control-Allow-Origin" solution often when connecting my Javascript Ajax code to the PHP backend on my server. However, nothing seems to work for Ionic. I've seen several questions/answers here on SO, as well as read some blogs, and they all say this should work but it doesn't.
I have complete control over my endpoint and have created a PHP file there that looks like this:

Answered 2020-Aug-10 at 19:27I found the problem and the fix. As expected it was in the Ionic App's code. But it was not quite what I expected. Hopefully, this may be useful to someone in the same predicament. The problem was this line:

QUESTION
ANSWER
Answered 2018-Feb-17 at 00:17We did big chat. Things which were helpful:
- Be sure that you completely delete all previous version with
npm uninstall -g ionic
or manually fromrm -rf /usr/local/lib/node_modules
. Don't forget remove symlink too:rm -rf /usr/local/bin/ionic
- After completely deletion you should see error: command not found of
ionic -v
- And now if your
npm root -g
path is right like/usr/local/lib/node_modules
try to installnpm install -g ionic@latest
. Then you should get correct output ofionic -v
QUESTION
I've been reading through this excellent post in an effort to better understand metaclasses, and encountered some behavior that confuses me.
Setup
...ANSWER
Answered 2019-Oct-23 at 18:53Although you are indeed correct that __call__
is a magic method that is handled specially by the interpreter, that special behavior is only triggered when you say A()
and implicitly delegate to the __call__
method. Saying A.__call__
executes in exactly the same way as a.foo
, meaning that it comes down to, as you said, AMeta.__call__
being a non-data descriptor and therefore being overwritten by the explicit definition of A.__call__
Unlike in Question 1, the interpreter's special handling of magic methods does get invoked here. However, including metaclasses complicates things a little. The test case is roughly equivalent to the below code without metaclasses:

I am in confusion when trying to understand the order that metaclass
creates a class instance. According to this diagram (source),
I type the following codes to verify it.
...ANSWER
Answered 2018-Nov-12 at 09:50Update 2: Based on behavior, the fact that M0.__call__
is called below must be a side effect of this line in builtin__build_class
in the CPython source (Python/bltinmodule.c
).
In order to define a class that has a metaclass, we call the metaclass's __prepare__
, __new__
, and __init__
as usual. This creates a class—in the example below, Meta
—that is callable, but its internal PyFunction_GET_CODE
slot points not to its own __call__
but rather to its metaclass's __call__
. Hence if we call Meta()
(the metaclass object), we invoke M0.__call__
:
