  • width:auto for <input> fields

    - by richb
    Newbie CSS question. I thought 'width:auto' for a display:block element meant 'fill available space'. However for an <input> element this doesn't seem to be the case. For example: <body> <form style='background-color:red'> <input type='text' style='background-color:green;display:block;width:auto'> </form> </body> Two questions then: Is there a definition of exactly what width:auto does mean? The CSS spec seems vague to me, but maybe I missed the relevant section. Is there a way to achieve my expected behaviour for a input field - ie. fill available space like other block level elements do? Thanks!

  • reverse many to many fields in Django + count them

    - by cleliodpaula
    I'm trying to figure out how to solve this class Item(models.Model): type = models.ForeignKey(Type) name = models.CharField(max_lenght = 10) ... class List(models.Model): items = models.ManyToManyField(Item) ... I want to count how many an Item appears in another Lists, and show on template. view def items_by_list(request, id_): list = List.objects.get(id = id_) qr = list.items.all() #NOT TESTED num = [] i = 0 for item in qr: num[i] = List.objects.filter(items__id = item__id ).count() #FINISH NOT TESTED c = {} c.update(csrf(request)) c = {'request':request, 'list' : qr, 'num' : num} return render_to_response('items_by_list.html', c, context_instance=RequestContext(request)) template {% for dia in list %} <div class="span4" > <div> <h6 style="color: #9937d8">{{item.type.description}}</h6> <small style="color: #b2e300">{{ item.name }}</small> <small style="color: #b2e300">{{COUNT HOW MANY TIMES THE ITEM APPEAR ON OTHER LISTS}}</small> </div> {% endfor %} This seems to be easy, but I could not implement yet. If anyone has some glue to me, please help me. Thanks in advance.

  • C++ Expose Already Existing Instance of Objects to a Scripting Language

    - by user947871
    So, I want to be able to modify already instanced C++ objects in a scripting language. I have been looking at Lua with LuaBind and Python with SWIG or Boost::Python, but all I see is how to make new instances of the objects, but I want to modify already existing ones. Example: C++: Player playerOne = new Player(); Scripting Language : playerOne.Transform.x += 5; Is this possible, and if so, wat would you suggest as a good Language/library to achieve this with?

  • How Can I Determine if HTTP Requests/Responses are compressed in IE7?

    - by DTS
    I'm trying to use Fiddler (v2.2.2.0) to see if HTTP traffic through IE7 is being compressed. I'm not seeing Accept-Encoding or Content-Encoding request/response headers being sent/returned and I do not need to decode the response data once it's arrived, which leads me to believe that the responses are NOT coming back compressed. However, when making the same requests using FireFox 3.5.7, I could see through FireBug that FF was sending Accept-Encoding and YSlow at least thought my data was coming back compressed. A comment in this question: http://stackoverflow.com/questions/897989/using-fiddler-to-check-iis-compression suggested that a proxy server may be to blame for stripping out headers and decompressing the content for security reasons. I am using Verizon FIOS for my broadband at home and am now wondering if Verizon is proxying my HTTP traffic? In short, how can I positively confirm/deny that responses are coming back compressed through IE? Thanks.

  • extracting multiple fields from a text file using php

    - by Dave
    Hi, what is the best way of extracting multiple (~40 values) from a text file using php? the data is more or less like: NAMEA valuea NAMEB valueb I'm looking for a proper* approach to extracting this data into a data-structure, because i will need to specify regexs for all of them (all 40). did i make myself clear? *meaning, the default/painful method would be for me to do: $namea = extractfunction("regexa", $textfilevalue); $nameb = extractfunction("regeb", $textfilevalue); ... 40 times!

  • php HTTP_REFERER header, how to turn off or leave blank

    - by eco_bach
    Hi I'm using the following simple PHP proxy script but am getting a sporadic message at the destination site. I'm thinking that perhaps it may have something to do with the HTTP_REFERER header, although I'm not explicitly defining it. Can anyone tell me how to explicitly turn off or leave the HTTP_REFERER header blank? Thanks in advance! $url = $_GET['path']; readfile($path);

  • Correct approach to validate attributes of an instance of class

    - by systempuntoout
    Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters declaration ? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

  • Rails - Searching multiple textboxes and fields

    - by ChrisWesAllen
    I have a model of events that has various information such as date, location, and description of whats going on. I would like for my users to be able to search through the events list through a set of different textboxes but I having a hard time getting the syntax just right in my view I have... <% form_tag users_path, :method => 'get' do %> (<%= text_field_tag :search_keyword, params[:search_keyword] %>) + (<%= text_field_tag :search_zip, params[:search_zip] %>) <%= submit_tag "Find Events!", :name => nil %> <% end %> and in the controller I'm trying to query through the results.... if params[:search_keyword] @events = Event.find(:all, :conditions => [' name LIKE ? ', "%#{params[:search_keyword]}%"]) elsif params[:search_zip] @events = Event.find(:all, :origin=> params[:search_zip], :within=>50 ) else @events = Event.find(:all) end How do I code it so that it will perform the search only if the textbox isnt empty? also if both textboxes are filled then @events should be the product of BOTH queries? if have no idea if this would work =(???@event = @event+ event.find.....???

  • How to get correct children ids using fields_for "parents[]", parent do |f| using f.fields_for :children, child ?

    - by Anatortoise House
    I'm editing multiple instances of a parent model in an index view in one form, as in Railscasts #198. Each parent has_many :children and accepts_nested_attributes_for :children, as in Railscasts #196 and #197 <%= form_tag %> <% for parent in @parents %> <%= fields_for "parents[]", parent do |f| <%= f.text_field :job %> <%= f.fields_for :children do |cf| %> <% cf.text_field :chore %> <% end %> <% end %> <% end %> <% end %> Given parent.id==1 f.text_field :job correctly generates <input id="parents_1_job" type="text" value="coding" size="30" name="parents[1][job]"> But cf.text_field :chore generates ids and names that don't have the parent index. id="parents_children_attributes_0_chore" name="parents[children_attributes][0][chore]" If I try passing the specific child object to f.fields_for like this: <% for child in parent.children %> <%= f.fields_for :children, child do |cf| %> <%= cf.text_field :chore %> <% end %> <% end %> I get the same. If I change the method from :children to "[]children" I get id="parents_1___children_chore" which gets the right parent_index but doesn't provide an array slot for the child index. "[]children[]" isn't right either: id="parents_1__children_3_chore" as I was expecting attributes_0_chore instead of 3_chore. Do I need to directly modify an attribute of the FormBuilder object, or subclass FormBuilder to make this work, or is there a syntax that fits this situation? Thanks for any thoughts.

  • C# equivalent of typeof for fields

    - by rwallace
    With reflection, you can look up a class from a string at run time, but you can also say typeof(Foo) and get compile time type checking, auto completion etc. If what you want is a field not a class, you can look it up from a string at runtime, but if you want compile time type checking etc., is there anyway to say something like fieldof(Foo.Bar)? I know the name of both the class and the field in advance, and I want to be able to refer to the field at compile time rather than with a run-time string lookup.

  • Java ME Runnable object takes up memory although not made an instance yet

    - by user1646684
    I am facing a strange problem with memory in Java ME. here is a part of my code: int variable=1; while (true) { if (variable==2) { display = Display.getDisplay(this); MyCanvas mc = new MyCanvas(this); // MyCanvas is a runnable object mcT = new Thread(mc); // new thread for MyCanvas mc.repaint(); display.setCurrent(mc); mcT.start(); // run thread } if (variable==1) { // Do some other stuff } } The problem is that although still the variable is set to 1, so it does not come through the if (variable==2) condition the program consumes 300kB more memory than when I delete the code after condition if (variable==2). As far as I know the code should by executed and the objects shall be created only when I set variable to value 2. But it consumes the memory also when the code after condition "if (variable==2)" is not executed. Why does this happen?

  • Fields in CakePHP could not be referred by JQuery

    - by kwokwai
    Hi all, I have got a simple HTMl form with one field as follows: <input type="text" name="data['User']['user_id']" id="data['User']['user_id']" value="1"> $(document).ready(function(){ $("#data['User']['user_id']").mouseover(function(){ alert("hello"); }); }); The code couldn't work, I think it may be the name of the Input text field that caused the problem, but I don't know how to alter it because this is the naming convention in CakePHP.

  • Disable form submission via Enter key on only _some fields

    - by justSteve
    I want to retain the conventional 'form submits when i press Enter' behavior because users are familiar with. But by reflex, they often hit enter when they finish with a text input box - but before they are actually done with the complete form. I'd like to hijack the Enter key only when then focus is on a certain class of input. Looking Related Questions this looks like what I'm looking for: if (document.addEventListener) { document.getElementById('strip').addEventListener('keypress',HandleKeyPress,false); } else { document.getElementById('strip').onkeypress = HandleKeyPress; } but the if (document.addEventListener) { is unfamiliar.

  • passing array fields to jquery ajax

    - by Rob Brandt
    I have a form I am submitting via jquery ajax. Early in the form, I have this field: <select name="inquirymodule[]" id="inquirymodule"> The user can add as many as they like, and all the selects go into the inquirymodule[] array. The jQuery looks like this: jQuery.ajax({ type: 'POST', url: 'ajax.php', dataType: 'json', data: { inquirymodule: jQuery("select[name='inquirymodule[]']").serialize(), }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('error'); } }); That works fine. Trying to do the same thing with a date, like this: <input class="formInput" type="text" id="startBreak0" name='startbreak[]' /> adding startbreak: jQuery("select[name='startbreak[]']").serialize() to the ajax call. It doesn't work, I cannot see why. Suggestions?
