iphone - Saving data from ViewControllres (Core Data) -

-

I have seen through the core data tutorial which puts the main data code in the appadiget class that was created to create a window project. I was already able to save and retrieve data from AdLite Class.

My question is, if I have a view controller that saves the data, then how do I save data for that specific class?

  • Do I continually redefine the store and managed object model in that class?
  • If this is the case, then what is the programmatic way to do this (already it was generated for me). I. What methods / Instantiable / Properties I need to declare? I

    can stand for any explanation

    No need to go through the app representative or redefine the store etc. All you need is in the context of managedObjectContext . Generally, this is a property (a view controller says), which you can set from outside to after creation and can easily reach within the visual controller class (much easier than going through the app representative !). You can easily pass it to other view controllers, and read with standard methods and write on core data.

    If you want to save your items, yes - you have to create your own managed object model (by modifying the template you have generated).

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...
