  • Post and Comment with the same Model.

    - by xRobot
    I have created a simple project where everyone can create one or more Blog. I want to use this models for Post and for Comment: class Post_comment(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField(_('object ID')) content_object = generic.GenericForeignKey() # Hierarchy Field parent = models.ForeignKey('self', null=True, blank=True, default=None, related_name='children') # User Field user = models.ForeignKey(User) # Date Fields date_submitted = models.DateTimeField(_('date/time submitted'), default = datetime.now) date_modified = models.DateTimeField(_('date/time modified'), default = datetime.now) title = models.CharField(_('title'), max_length=60, blank=True, null=True) post_comment = models.TextField(_('post_comment')) markup = models.IntegerField(choices=MARKUP_CHOICES, default=DEFAULT_MARKUP, null=True, blank=True) if it is a comment the parent is not null. So in most case the text field will contain a little bit of text. Can I use this model for both Post and Comment ?

  • SQL tables using VARCHAR with UTF8 (with respect to multi byte character length)

    - by Elius
    Like in Oracle VARCHAR( 60 CHAR ) I would like to specify a varchar field with variable length depending on the inserted characters. for example: create table X (text varchar(3)) insert into X (text) VALUES ('äöü') Should be possible (with UTF8 as the default charset of the database). On DB2 I got this Error: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001 (Character data, right truncation occurred; for example, an update or insert value is a string that is too long for the column, or a datetime value cannot be assigned to a host variable, because it is too small.) I'm looking for solutions for DB2, MsSql, MySql, Hypersonic.

  • Using xval with fields containing periods

    - by JP
    Hello, I have been using xVal with success for a while but this evening ran into an issue where a field containing a period would not be validated (client or server-side). I am using ASP.NET MVC2 and need to use the period syntax in cases where I am model binding to a list. In the below example I am using a textbox for the sake of simplicity: xVal.AttachValidator(null, { "Fields": [{ "FieldName": "entry[622592].Value", "FieldRules": [{ "RuleName": "Required", "RuleParameters": {}}]}] }, {}) <input type="text" class="text" name="entry[622592].Value"/> If I replace both instances of "entry[622592].Value" to something trivial like "test" then the validation works successfully, but if i leave it this way the validation never appears to fire... Has anyone run into this issue? Thanks in advance!

  • Javascript auto calculating with (+) and (-)

    - by Josh
    I need some help finding the error in my javascript calculation. I need to calculate the sum of my input boxes automatically and have my user be able to edit the calculation using + or - buttons. The code I have already does the calculation automatically if you manually enter the numbers, but pressing the + or - does not change the calculation. Here is the code: <html> <head> <script language="javascript"> function Calc(className){ var elements = document.getElementsByClassName(className); var total = 0; for(var i = 0; i < elements.length; ++i){ total += parseInt(elements[i].value); } document.form0.total.value = total; } function addone(field) { field.value = Number(field.value) + 1; } function subtractone(field) { field.value = Number(field.value) - 1; } </script> </head> <body> <form name="form0" id="form0"> 1: <input type="text" name="box1" id="box1" class="add" value="0" onKeyUp="Calc('add')" onChange="updatesum()" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box1);"> <input type="button" value=" - " onclick="subtractone(box1);"> <br /> 2: <input type="text" name="box2" id="box2" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box2);"> <input type="button" value=" - " onclick="subtractone(box2);"> <br /> 3: <input type="text" name="box3" id="box3" class="add" value="0" onKeyUp="Calc('add')" onClick="this.focus();this.select();" /> <input type="button" value=" + " onclick="addone(box3);"> <input type="button" value=" - " onclick="subtractone(box3);"> <br /> <br /> Total: <input readonly style="border:0px; font-size:14; color:red;" id="total" name="total"> </form> </body></html> Im sure the issue must be small, I just cant put my finger on it.

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • Getting SharePoint absolute site url

    - by Francis
    I need to get the current absolute url of my site from inside an aspx page (no codebehind). I tried $SPUrl, but it get's converted into a relative url. <asp:Literal runat="server" text="<% $SPUrl:~Site/mypage.aspx %>" /> results in "/mypage.aspx". It's important that I get the full absolute url starting with "http://". <asp:Literal runat="server" text="<% $SPUrl:~SiteCollection/mypage.aspx %>" /> does the same. The goal is to get this url: "http://myspweb.com/mypage.aspx" as result.

  • JavaScript Coding for Finding Shipping Total

    - by user2913279
    I am having a very hard time with this code. I have been working on it for days and cannot seem to figure it out. Please help!! Here are the specific I need for the code: Many companies normally charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00. For any orders over $25.00, add 10% to the total purchase price for shipping and handling, but do not include the $1.50 minimum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Here is the code I have: <!DOCTYPE> <head> <title>Calculate Shipping</title> <script type="text/javascript"> function parseInt() { var salesPrice = document.salesForm.Price.value; var minCharge = salesPrice + 1.50; var shipping = salesPrice * 10/100; if (salesPrice <= 25) window.alert('Your sales total including shipping is $' + minCharge); else window.alert('Your sales total including shipping is $' + salesPrice + shipping); } </script> </head> <body> <form name="salesForm"> <div > <p>Enter Your Purchase Price</p> <input type="text" name="Price" /><br /><br /> <input type="button" name="Calculate" value="Calculate Shipping" onclick="parseInt ()" /> </div> </form> </body> </html> Everything works except for the math in the alert box. It will show an incorrect total...

  • How to use jQuery to generate 2 new associated objects in a nested form?

    - by mind.blank
    I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

  • How to get "printer ready bytes" from a source in c#?

    - by luis_villase
    Hey everyone! I'm in a bit of trouble here, hoping you can help a fellow programmer out. I have an application that receives a pointer to raw bytes (plus length and stuff) and sends said raw data to a printer. This is important, I have no choice but to use this method to get any printing done. If I send a raw string, it will print with no problem. However, I need to be able to print formatted text, images, etc. So the thing is... I would like to be able to get printer ready bytes from a given source (maybe a pdf, or html, does not matter as long as it contains formatted text and/or images). It would be like "splitting" the print command like so: a) Open file and read data b) Load printer data into memory c) Send bytes to printer Obviously, I've got a) and c) covered, it's b) the one that's breaking my head. Any thoughts? Thanks in advance for your help.

    This is a link in an HTML email.. Other links in this email work, but this one does not get recognized in a BlackBerry as a link, so you can't click on it. Does anyone know why that might be?

  • MySQL storage engine dilemma

    - by burntblark
    There are two MySQL database features that I want to use in my application. The first is FULL-TEXT-SEARCH and TRANSACTIONS. Now, the dilemma here is that I cannot get this feature in one storage engine. It's either I use MyIsam (which has the FULL-TEXT-SEARCH feature) or I use InnoDB (which supports the TRANSACTION feature). I can't have both. My question is, is there anyway I can have both features in my application before I am forced to make a choice between the two storage engines.

    Hello! When I installed perl from the source the first nice surprise was that without doing something all module installed from now on were available to the new perl. Since I didn't find one module on cpan that comes with my OS I have to use for some scripts the onboard-perl. For one of these scripts I would like to install Text::Format or Text::Autoformat (didn't find the docu for that module on cpan). My question: how can I tell cpan to install the module this one time for the OS-distro-perl?

  • How to write a program that mimics Fiddler by using tcpdump or from scratch?

    - by ????
    When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

  • databinding to self without code

    - by jcollum
    I'm building a UserControl in WPF. The control has two properties, Title and Description, that I'd like to bind to two textblocks. Seems real straightforward, and I got it working, but I'm curious about something. To get it to work I had to add this code: void CommandBlock_Loaded(object sender, RoutedEventArgs e) { this.DataContext = this; } My bindings look like this: <TextBlock Text="{Binding Title}" Width="100" ... /> <TextBlock Text="{Binding Description}" Width="100" ... /> What I'm wondering is how come I couldn't get it to work without the this.DataContext = this; and instead use DataContext="{Binding RelativeSource={RelativeSource Self}}" (in the UserControl element of the markup)? I'm sure I'm missing something about DataContexts but don't know what.

  • Java - Does null variable require space in memory

    - by Yatendra Goel
    class CheckStore { private String displayText; private boolean state; private String meaningfulText; private URL url; public CheckStore(String text, boolean state) { this.displayText = text; this.state = state; } : : } As I am initializing only two variables (displayText and state) in the constructor, Will the rest two variables (meaningfulText and url which will have the value null) will require space in memory to store null value. Q1. I think they will require space. If they will, then how much memory does a null value takes in the memory (like int takes 4 bytes). Q2. How much space a string takes in memory. I guess it will depend on the length of the string. So how much space a string takes of how much length?
