• Django admin- constrain visibility of models and model instances based on who logged in

  - by theactiveactor

  Using the django admin, I would like to be able to specify which models a user sees when he logs in. For a stretch goal, for each model types a user can see, I would like to specify a filter to limit which instances of the model the user can see. Could someone please provide a pointer for how to go about achieving this?

• grails set bean value from radio button

  - by Jeff Storey

  I'm somewhat new to grails (not groovy though) and I'm working on a sample CRUD application. The issue I'm trying to solve is how to set a property on a bean based on a radio button before I update it in the database. Is the Form Helper http://www.grails.org/plugin/form-helper plugin the way to go? Will the bean have its value set regardless of if the button is actually clicked by the user or if it is left at its default value? thanks, Jeff

• What is the difference between a "service account" and an "installed application"?

  - by TheBeatlemaniac

  To my understanding, the main difference is that a service account doesn't require a user to log in for authorization, while an installed application does. I am making an Android app (an "installed application"?) that offers an in-app subscription, and doesn't require the user to log in to an account (a "service account"?). To get a Client ID for the Google Play Developer API, I have to declare it as either an installed application or a service account, and am unsure which to go with.

• What does "Computing additional info" mean?

  - by JesperE

  Eclipse Helios periodically starts running a job which displays "Computing additional info". During this time, Eclipse is very sluggish, bordering on unusable. What does this job do? Can I shut it off? I just hope that someone in the JDT team comes to sense and gets rid of it, make it go faster, or at the very least change it to something meaningful.

• Pylons error handling

  - by TJ Huffington

  Hello, I am just getting started with Pylons and am confused as to how to account for exceptions. What is the proper way to error check user input (ensure a correct email address, check that it doesn't yet exist in the database, etc ...)? Should these checks go inside the model classes or somewhere else? Sample code would be great.

  In Eclipse, is there a way you can set Method Breakpoints on all the methods of the class without going to individual methods? The motivation behind is that, any time a method gets hit, it would go to that method in debug mode.

• Prolog: Error Handling and Find Unique

  - by anotherstat

  Given: fruitid('Apple', 'Granny Smith', 1). fruitid('Apple', 'Cox', 2). fruitid('Pear', 'Bartlett', 3).

• Toast versus Dialog boxes: which to use when?

  - by Samuh

  The answer could be subjective. The answer could be intuition. And I guess the answer could be found from the traditional modal versus non-modal debates. But in general how do you generally decide which one to go for? What are their use cases? Thanks.

• Does a HashMap retain the order of its elements on the next read if it is constructed as a LinkedHas

  - by javanix

  Suppose I have a Java method that returns a HashMap object. Because a LinkedHashMap is a subclass of HashMap, I can return a LinkedHashMap from this method just fine. On the next "read" action (no adding/removing/modifying of K/V pairs), would iterating over the keys of the resulting method (which returns a HashMap) go in the same order as the originating LinkedHashMap, even though the HashMap lacks the key links?

• What to put in a python module docstring?

  - by 007brendan

  Ok, so I've read both PEP 8 and PEP 257, and I've written lots of docstrings for functions and classes, but I'm a little unsure about what should go in a module docstring. I figured, at a minimum, it should document the functions and classes that the module exports, but I've also seen a few modules that list author names, copyright information, etc. Does anyone have an example of how a good python docstring should be structured?
