python - What exactly are Django Apps -

-

I have to switch from trains to diego, to expand my mind, and a question arises in my mind.

My train app is quite messy, because my hobby based development approach is a patch and glue. I have seen very quickly that Django is split between a project and an app according to your site, a project multiple applications , And an app can be used for many apps.

This made me amazed, because it will clarify the rows between the areas of my site. I tried to find some more examples and information on it, but I could not answer my question, Which is:

How big / small is this app? Do they want to communicate close / near?

For example, is an app to deal with the profiles of smart users, and is another app for dealing with blog posts and comments of those users? (In my site, a user can have many blogs, with different profiles). Or are they meant to be used otherwise?

is a fancy name for a degeneracy app a Python package actually , That's the only thing that separates a Denggo app from other Python packages, it makes sense to appear in the INSTALLED_APPS list in settings.py Because it has things like templates, models, or other features which can be searched automatically through other DJG facilities.

A good appendix app will do only one thing, do it well, and it should not be tightly connected to any other app, so that it can be used. contrib Many types of apps are provided with the names in the namespace following this scenario.

In your example, there is a good way to create applications that the user has to be one for profile (or use one of several existing profile apps), an app for blog posts (or none of these Many who already do), an app for comments, separated from the blog post (again, you can use an existing app for this), and finally, a very small app that all three together Adds because they are different Should not be directly dependent.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
