  • Listing the content of a tar file or a directory only down to some level

    - by Tim
    I wonder how to list the content of a tar file only down to some level? I understand tar tvf mytar.tar will list all files, but sometimes I would like to only see directories down to some level. Similarly, for the command ls, how do I control the level of subdirectories that will be displayed? By default, it will only show the direct subdirectories, but not go further.

  • [Django] How do I filter the choices in a ModelForm that has a CharField with the choices attribute

    - by nubela
    I understand I am able to filter queryset of Foreignkey or Many2ManyFields, however, how do I do that for a simple CharField that is a Select Widget (Select Tag). For example: PRODUCT_STATUS = ( ("unapproved", "Unapproved"), ("approved", "Listed"), #("Backorder","Backorder"), #("oos","Out of Stock"), #("preorder","Preorder"), ("userdisabled", "User Disabled"), ("disapproved", "Disapproved by admin"), ) and the Field: o_status = models.CharField(max_length=100, choices=PRODUCT_STATUS, verbose_name="Product Status", default="approved") Suppose I wish to limit it to just "approved" and "userdisabled" instead showing the full array (which is what I want to show in the admin), how do I do it? Thanks!

  • Including some static html files?

    - by user246114
    Hi, Where can we place static html files in our war file? For example, a default project has this: war/projectname.html I'd like to just make a few static folders with static pages that are like: war/projectname.html war/signup/index.html war/about/index.html so that my users can just hit those static pages like: www.myproject.com/signup www.myproject.com/about where would I put folders like that in our project tree? I tried putting them under war/, just beside projectname.html (like above), but they don't seem to be available there, I just get a 404 error, Thanks

  • Rails: i would need to load a haml file in a class and render in the caller

    - by Totty
    I have this: app/modules/grid_module.rb app/modules/grid.html.haml then in my view: app/views/layouts/default.html.haml I want to make a new instance of the grid_module and render it content. Its content is into the grid.html.haml and this file can only use the instance vars set in the grid_module.rb is this possible to do? (the grid name is just an example, it must be more flexible, to load the html.haml file based on the .rb class) the grid_module must has access to models too* like this: User.find_by_id(4) thanks for help

    - by heap
    This object always uses the default on the system, so on an x64 machine, it will use an x64 Internet Explorer object. Is there any way I can force it to use the x86 IE? The web page element the browser accesses does not work on x64 and is out of my control.

  • How do I programmatically apply a Drupal input filter?

    - by ford
    I am currently exporting Drupal data to an external source (XML) programmatically. However, I want the data to run through the site's default Input Format (the filter that runs before user content is displayed on the website) before being written to file. How do I programmatically apply a Drupal input filter? Is there a specific function call or hook for this purpose? If so, links/advice would be most appreciated.

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.
