render

问题 I have 3 model user, post and comment. the user can have multiple post and comments. I need to produce the JSON for last 50 post only. I am not using rails convention, so i have to write that in neewsfeed_controller. Thank for the support. class NewsfeedsController < ApplicationController respond_to :json def build @posts = Post.all.order("created_at DESC") render json: {:event => @posts} end def data @posts = Post.all.order("created_at DESC") render :partial => "newsfeeds/data.json" end

问题 I have a form that I'd like to use in several pages of my website. So I call the method like that in my page: {{ render(controller('ProjectApplicationBundle:Application:form')) }} And I have my formAction method: public function formAction() { $form = $this->createForm($type,$obj); if('POST' == $this->getRequest()->getMethod()){ $form->submit($this->getRequest()); if($form->isValid()){ //redirect to a page after the form } } //render the form template ... } This is not my code, this is just

问题 i have a problem with res.render() in expressjs i use ajax to request on this route: route.get('/about',authentication,(req,res)=>{ res.render('about'); }); I did some search and found out that res.render does not work with ajax calls so how can I change and render page without res.render() . If I remove the res.render and console.log it it will work actually any code work but not res.render (by clicking a link I send a token in header with ajax request then in my route I have an

问题 So say you want to have an abstract class called play, which has a render method. public abstract class RenderPanel{ public abstract void render(); } And then you have another class which calls the render method using some sort of game loop. public class Window implements Runnable{ public void run(){ while(running){ RenderPanel.render(); Thread.sleep(5000); } } } This code would not work because you cannot call an abstract class statically, and you can't instantiate the class. So how would

问题 I've read several posts on this but nothing that would really answer my question in an up-to-date way (i.e. UI.insert is depreciated). So what's the best way of inserting/rendering a Template into a Surface reactively, meaning, not only one data object (renderWithData), but whatever is defined in the Template.helpers should also be updated reactively. Code tried so far: var div = document.createElement('div'); //UI.insert(UI.render(function() { return Template.hello; }), div); surface = new

问题 What is the most speedy way and accurate to render non-anti-aliased fonts (e.g. ttf fonts) using Python to an internal image (e.g. to a PIL.Image , i.e. I don't need to display it)? I say accurate because I tried it with pygame a while back and the rendered fonts at the size I gave it didn't match what windows rendered in Word or Paint. 回答1: Python Imaging Library (PIL) can render text to an image--I'm not aware of it being inaccurate , but I haven't fully tested it yet... Example from a pre

问题 Is there a way to tell an entire controller to render a particular partial or text? Example: class PageNotesController < ApplicationController render :text => "Testing" def index @notes = PageNotes.all end def show @note = PageNotes.find(params[:id]) end def create @note = PageNotes.create(params[:note]) end end Now obviously I can go into each individual method and tell it to render something, but I was just curious to know if this is possible. Thanks in advance! 回答1: you can tell an entire

问题 Is it even possible to continue rendering and updating while resizing the window so that it doesn't stretch? 回答1: This is pretty deeply baked into XNA's Game class's behaviour. I'm dealing with this exact problem now, but I don't have a good solution yet. EDIT: I how now found a solution - but it doesn't answer the bit about scaling - so I've posted it as a question/answer pair over here. You could possibly dive in with reflection and disconnect the events that pause the game's timer when you

问题 Okay, so I am making a multiple choice quiz game with python and pygame. However, I am done with the start screen and trying to make the question screen. I simply can't figure out why the text doesn't render. Here's my code: enter_pressed = False random_question = random.randrange(1, 3) question_number = 0 # Sets the height and width of the screen size = [720, 575] screen = pygame.display.set_mode((size),pygame.FULLSCREEN) # The Caption for the display pygame.display.set_caption("Quiz") #
