  • How do I rescue from a `require': no such file to load in ruby?

    - by René Nyffenegger
    I am trying to rescue from a `require': no such file to load in ruby in order to hint the user at specifying the -I flag in case he has forgotten to do so. Basically the code looks like: begin require 'someFile.rb' rescue puts "someFile.rb was not found, have you" puts "forgotten to specify the -I flag?" exit end I have expected the rescue part to take over execution in case someFile.rb was not found, but my assumption was wrong.

  • 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

  • Adding object to child collection causes entire collection to load in Fluent NHibernate.

    - by Mike C.
    Hello, I have my Parent object, which contains an ICollection of Children objects. The Children are lazy loaded and I do not need them in the context of my scenario. However, when I try to add a new child object to my Children collection, it kicks off the lazy load and loads all 7000 child records. I assume I am making a newbie mistake. Anybody out there know how I can fix this? Thanks!

  • SpriteFont Exception, no such character?

    - by Michal Bozydar Pawlowski
    I have such spriteFont: <?xml version="1.0" encoding="utf-8"?> <!-- This file contains an xml description of a font, and will be read by the XNA Framework Content Pipeline. Follow the comments to customize the appearance of the font in your game, and to change the characters which are available to draw with. --> <XnaContent xmlns:Graphics="Microsoft.Xna.Framework.Content.Pipeline.Graphics"> <Asset Type="Graphics:FontDescription"> <!-- Modify this string to change the font that will be imported. --> <FontName>Segoe UI</FontName> <!-- Size is a float value, measured in points. Modify this value to change the size of the font. --> <Size>20</Size> <!-- Spacing is a float value, measured in pixels. Modify this value to change the amount of spacing in between characters. --> <Spacing>0</Spacing> <!-- UseKerning controls the layout of the font.

(0x0441) is not available in this SpriteFont. If applicable, adjust the font's start and end CharacterRegions to include this character. Parameter name: character Why? I'm drawing the string like this: spriteBatch.DrawString(font24, zasadyText, zasadyTextPos, kolorCzcionki1, -0.05f, Vector2.Zero, 1.0f, SpriteEffects.None, 0.5f) I even changed the spriteFont to cyrillic: <CharacterRegions> <CharacterRegion> <Start>&#09;</Start> <End>&#09;</End> </CharacterRegion> <CharacterRegion> <Start>&#0032;</Start> <End>&#0383;</End> </CharacterRegion> <CharacterRegion> <Start>&#1040;</Start> <End>&#1111;</End> </CharacterRegion> </CharacterRegions> </Asset> </XnaContent> and it still doesn't work. I got the (0x441 = char) exception -- EDIT -- Ok, I got the solution. It was a letter mistake in language. I had this: if (jezyk == "ru_RU") { font14 = Content.Load<SpriteFont>("ru_font14"); font24 = Content.Load<SpriteFont>("ru_font24"); font12 = Content.Load<SpriteFont>("ru_czcionkaFloty"); font10 = Content.Load<SpriteFont>("ru_font10"); font28 = Content.Load<SpriteFont>("ru_font28"); font20 = Content.Load<SpriteFont>("ru_font20"); } else { font14 = Content.Load<SpriteFont>("font14"); font24 = Content.Load<SpriteFont>("font24"); font12 = Content.Load<SpriteFont>("czcionkaFloty"); font10 = Content.Load<SpriteFont>("font10"); font28 = Content.Load<SpriteFont>("font28"); font20 = Content.Load<SpriteFont>("font20"); } and there should be not "ru_RU" but "ru-RU" I have no idea. I changed the spriteFont to cyrillic: <CharacterRegions> <CharacterRegion> <Start>&#09;</Start> <End>&#09;</End> </CharacterRegion> <CharacterRegion> <Start>&#0032;</Start> <End>&#0383;</End> </CharacterRegion> <CharacterRegion> <Start>&#1040;</Start> <End>&#1111;</End> </CharacterRegion> </CharacterRegions> </Asset> </XnaContent> and it still doesn't work.

  • How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

    - by Clem
    Hi, I am using the Orbeon Forms solution to generate messages from filled-in web forms. I read different code snippetse in Orbeon's wiki on XForms submission from a pipeline, and I tried different solutions but it doesn't work, and there is no example with a POST from a pipeline, caught by a PFC and sent to an XForms view that receives the posted data (all examples are done in the same page). I have the following pipeline which is received on his instance input: pipelineWrite.xpl <p:config ...> <p:param name="instance" type="input"/> <!-- instance containing the data of the form filled by user --> <p:param name="data" type="output"/> <p:processor name="oxf:java"> <!-- transforms the data into a file --> <p:input name="config"> <config sourcepath="." class="ProcessorWriteCUSDECCD001B"/> </p:input> <p:input name="input" href="#instance"/> <p:output name="output" id="file"/> <!-- XML containing the url of the file --> </p:processor> <p:processor name="oxf:xforms-submission"> <!-- post the XML to the success view --> <p:input name="submission"> <xforms:submission method="post" action="/CUSDECCD001B/success" /> </p:input> <p:input name="request" href="#file"/> <p:output name="response" ref="data"/> </p:processor> </p:config> Then there is the PFC which catch the actions : page-flow.xml <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/CUSDECCD001B/" view="View/ViewForm.xhtml"/> <!-- load the form to be filled in by user --> <page path-info="/CUSDECCD001B/write" model="Controller/PipelineWrite.xpl"/> <!-- send the instance of the form filled to the pipeline above --> <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/> <!-- send the instance containing the url of the file to the success view --> <epilogue url="oxf:/config/epilogue.xpl"/> </config> Then there is the success view, which is very simple : ViewSuccess.xhtml <html ... > <head> <title>Generation OK</title> <xforms:model> <xforms:instance id="FILE" src="input:instance"> <files xmlns=""> <file mediaType="" filename="" size="" /> </files> </xforms:instance> </xforms:model> </head> <body> Click here to download : <xforms:output ref="//file" appearance="xxforms:download"> <xforms:filename ref="@filename"/> <xforms:mediatype ref="@mediatype"/> <xforms:label>Download</xforms:label> </xforms:output> </body> </html> The problem is that the post is done well, the PFC catches the action well, load the correct view, but the view is loaded with no data (the view doesn't find the data on his instance input). I tried with a GET in the view to retrieve the POST data, and that's the same thing. No data is retrieved. So the download button doesn't work. I hope I'm clear enough to find a solution. Thanks in advance.

  • XNA: Best way to load and read a XML file?

    - by Rosarch
    I'm having difficulty doing this seemingly simple task. I want to load XML files with the same ease of loading art assets: content = new ContentManager(Services); content.RootDirectory = "Content"; Texture2d background = content.Load<Texture2D>("images\\ice"); I'm not sure how to do this. This tutorial seems helpful, but how do I get a StorageDevice instance? I do have something working now, but it feels pretty hacky: public IDictionary<string, string> Get(string typeName) { IDictionary<String, String> result = new Dictionary<String, String>(); xmlReader.Read(); // get past the XML declaration string element = null; string text = null; while (xmlReader.Read()) { switch (xmlReader.NodeType) { case XmlNodeType.Element: element = xmlReader.Name; break; case XmlNodeType.Text: text = xmlReader.Value; break; } if (text != null && element != null) { result[element] = text; text = null; element = null; } } return result; } I apply this to the following XML file: <?xml version="1.0" encoding="utf-8" ?> <zombies> <zombie> <health>100</health> <positionX>23</positionX> <positionY>12</positionY> <speed>2</speed> </zombie> </zombies> And it is able to pass this unit test: internal virtual IPersistentState CreateIPersistentState(string fullpath) { IPersistentState target = new ReadWriteXML(File.Open(fullpath, FileMode.Open)); return target; } /// <summary> ///A test for Get with one zombie. ///</summary> //[TestMethod()] public void SimpleGetTest() { string fullPath = "C:\\pathTo\\Data\\SavedZombies.xml"; IPersistentState target = CreateIPersistentState(fullPath); string typeName = "zombie"; IDictionary<string, string> expected = new Dictionary<string, string>(); expected["health"] = "100"; expected["positionX"] = "23"; expected["positionY"] = "12"; expected["speed"] = "2"; IDictionary<string, string> actual = target.Get(typeName); foreach (KeyValuePair<string, string> entry in expected) { Assert.AreEqual(entry.Value, expected[entry.Key]); } } Downsides to the current approach: file loading is done poorly, and matching keys to values seems like it's way more effort than necessary. Also, I suspect this approach would fall apart with more than one entry in the XML. I can't imagine that this is the optimal implementation.
