  • Rails render partial with block

    - by brad
    I'm trying to re-use an html component that i've written that provides panel styling. Something like: <div class="v-panel"> <div class="v-panel-tr"></div> <h3>Some Title</h3> <div class="v-panel-c"> .. content goes here </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> So I see that render takes a block. I figured then I could do something like this: # /shared/_panel.html.erb <div class="v-panel"> <div class="v-panel-tr"></div> <h3><%= title %></h3> <div class="v-panel-c"> <%= yield %> </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> And I want to do something like: #some html view <%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %> <p>Here is some content to be rendered inside the panel</p> <% end %> Unfortunately this doesn't work with this error: ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN old_output_buffer = output_buffer;;@output_buffer = ''; __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s) on line #1 of app/views/sessions/new.html.erb: 1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%> ... So it doesn't like the = obviously with a block, but if I remove it, then it just doesn't output anything. Does anyone know how to do what I'm trying to achieve here? I'd like to re-use this panel html in many places on my site.

  • Generic IBindingListView Implementations

    - by Brad Leach
    Can anyone suggest a good implementation of a generic collection class that implements the IBindingListView & IBindingList interfaces and provides Filtering and Searching capabilities? I see my current options as: Using a class that someone else has written and tested Inheriting from BindingList, and implementing the IBindingListView interfaces Write a custom collection from scratch, implementing IBindingListView and IBindingList. Obviously, the first option is my preferred choice. Thanking you.

  • A scheme for expiring downloaded content?

    - by Chad Johnson
    I am going to offer a web API service that allows users to download and "rent" content for a monthly subscription fee. The API will either be open to everyone or possibly just select parties (not sure yet). Each developer must agree to a license, and they receive a developer key for their person. Each software application will have its own key as well. So then end-users will download the software which will interact with my service's API. Each user will have a key for each application as well (probably using OAuth). Content will be cached on first download and accessible offline via just the third-party application that cached the content. If a user cancels their subscription, I plan on doing the following: Deactivate the user's OAuth key for all applications. Do not allow the user's account to download new content via the API (and subsequently any software that uses the API). Now, the big question is: how do I make content expire if they cancel their subscription? If they cancel, they should not have access to content anymore. Here are ideas I've thought of (some of these are half-solutions, not yet fully fleshed out): Require that applications encrypt downloaded content using the user's OAuth key, making it available to only the application. This will prevent most users from going to the cache directory and just copying and keeping files. Update the user's key once a month, forcing content to re-cache on a monthly basic. Users could then access content for a month after they cancel their subscription. Require applications to "phone home" [to the service] periodically and check whether the user's subscription has terminated. If so, require in the API developer license that applications expire cache. If it is found that applications do not comply, their keys (and possibly keys for all developers) are permanently deactivated as a consequence. One major worry is that some applications may blatantly ignore constraints of the license. Is it generally acceptable to rely on applications abiding by the licensing constraints? Bad idea? Any other ideas? Maybe a way to make content auto-expire after x days? Something else? I'm open to out-of-the-box ideas.

  • Creating a Ruby method that pads an Array

    - by CJ Johnson
    I'm working on creating a method that pads an array, and accepts 1. a desired value and 2. an optional string/integer value. Desired_size reflects the desired number of elements in the array. If a string/integer is passed in as the second value, this value is used to pad the array with extra elements. I understand there is a 'fill' method that can shortcut this - but that would be cheating for the homework I'm doing. The issue: no matter what I do, only the original array is returned. I started here: class Array def pad(desired_size, value = nil) desired_size >= self.length ? return self : (desired_size - self.length).times.do { |x| self << value } end end test_array = [1, 2, 3] test_array.pad(5) From what I researched the issue seemed to be around trying to alter self's array, so I learned about .inject and gave that a whirl: class Array def pad(desired_size, value = nil) if desired_size >= self.length return self else (desired_size - self.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) The interwebs tell me the problem might be with any reference to self so I wiped that out altogether: class Array def pad(desired_size, value = nil) array = [] self.each { |x| array << x } if desired_size >= array.length return array else (desired_size - array.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) I'm very new to classes and still trying to learn about them. Maybe I'm not even testing them the right way with my test_array? Otherwise, I think the issue is I get the method to recognize the desired_size value that's being passed in. I don't know where to go next. Any advice would be appreciated. Thanks in advance for your time.

  • Doing a join across two databases with different collations on SQL Server and getting an error.

    - by Andrew G. Johnson
    I know, I know with what I wrote in the question I shouldn't be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn't aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it's a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all "normal" latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need. Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases. Exact error is: Cannot resolve the collation conflict between "SQL_Latin1_General_CP850_CI_AI" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

  • NHibernate collections: many-to-many relationships

    - by Brad Heller
    I've got two models, a Product model and a ShoppingCart model. The ShoppingCart model has a collection of products as a property called Products (List). Here is the mapping for my ShoppingCart model. <class name="MyProject.ShoppingCart, MyProject" table="ShoppingCarts"> <id name="Id" column="Id"> <generator class="native" /> </id> <many-to-one name="Company" class="MyProject.Company, MyProject" column="CompanyId" /> <property name="ExternalId" column="GUID" generated="insert" /> <property name="Name" column="Name" /> <property name="Total" column="Total" /> <property name="CreationDate" column="CreationDate" generated="insert" /> <property name="UpdatedDate" column="UpdatedDate" generated="always" /> <bag name="Products" table="ShoppingCartContents" lazy="false"> <key column="ShoppingCartId" /> <many-to-many column="ProductId" class="MyProjectMyProject.Product, MyProject" fetch="join" /> </bag> </class> When I try to save to the DB, the ShoppingCart is saved, but the mapping rows in ShoppingCartContents aren't save, making me thing that there's an issue with the mapping. Where am I going wrong here?

  • Test iPhone in-app purchases on a different bundle?

    - by Andrew Johnson
    We have a group of beta testers for iPhone app. Recently, we added in-app purchases to the app. Before this, we would send out ad hoc builds to beta testers using a separate bundle ID and name so that they could have the store build and the ad hoc build on their phones. However, it seems like we have to build the ad hoc copy with the same Bundle ID to test in-app purchases, and this means we can't send out a seperate beta copy - our beta file (annoyingly) overwrites the user's store-bought app. Is there any way to test in-app purchases in a different bundle ID? Do I need to set up fake, test in-app purchases for the test build too?

  • How do I test how my client program will react to a web server error?

    - by Brad Bruce
    I have a client program based on LibCurl. I have run into a situation where on some occasions a program on the server runs longer than the configured IIS timeout. IIS then terminates the program and returns a 502 error status to the client. I have added code to the client to capture this issue. Now, I need to find a way to prove that the change will work. I haven't been able to reliably reproduce the issue, so don't have a good test case. Any suggestions?

  • need to refresh web page after clicking close on pop-up window

    - by Brad
    I have a pop-up window a user logs into, once they are logged in successful, I have a message that has a link to close the window. But I want it to not only close that pop up window, but I want it to refresh the webpage the pop-up window was clicked on. So the page can refresh to see that there is a valid login session for that user. Is this possible w/ jQuery?

  • How can I make a resizable array in Java?

    - by Soren Johnson
    What is the best way to do a resizable array in Java? I tried using Vector, but that shifts all elements over by when when you do an insert, and I need an array that can grow but the elements stay in place. I'm sure there's a simple answer for this, but I still not quite sure.

  • PHP: How can I eliminate quotes around output from CSV file?

    - by brian johnson
    This code: <?php $curl=curl_init(); curl_setopt ($curl,CURLOPT_URL,"http://download.finance.yahoo.com/d/quotes.csv?s=XIN&f=l1c1p2rj1y&e=.csv"); curl_setopt ($curl,CURLOPT_HEADER,0); ob_start(); curl_exec ($curl); curl_close ($curl); $data=ob_get_clean(); $data = explode(",",$data); foreach ($data as $results) echo "<td>$results</td>"; ?> yields these results in my browser: 2.80 +0.02 "+0.72%" 1.85 204.2M 1.44 How can I have this PHP code above eliminate the quotations around the "+0.72%" so the end result is just: 0.72% ?

  • Where are the new languages?

    - by Johnson William
    Most now mainstream/popular (interpreted|scripting) programming languages were created around the 1990's. (Perl, Python, Ruby, PHP just to name a few). How many people knew about those languages around 1-2 years after they had been first published? Are there languages with potential of becoming as important as e.g.: Python or PHP being developed at the moment? I mean ... is there someone even seriously trying to create a new one? If the first version of a programming language is published and nearly nobody knows about it, as it was with all the languages I've mentioned above, where could I find out? Is there some sort of "list" or "network" dealing just with non-language-specific news? Is the area where Perl, Python, Ruby and PHP fit in already fully covered? Do you know of concrete examples of new programming languages being seriously developed or rising at the moment? (Except Google's go!)

  • safari and gzip

    - by brad
    I'm loading jQuery from google on my site (http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js) which is minned and gzip'd. In firefox, the jquery file shows as a 19k request, but Safari shows it as a 56k request. I'm assuming then that Safari is not accepting it as a gzip'd file. What's the deal? It's coming from google and I'm pretty sure it's supposed to be gzip'd

  • How do I implement graphs and graph algorithms in a functional programming language?

    - by brad
    Basically, I know how to create graph data structures and use Dijkstra's algorithm in programming languages where side effects are allowed. Typically, graph algorithms use a structure to mark certain nodes as 'visited', but this has side effects, which I'm trying to avoid. I can think of one way to implement this in a functional language, but it basically requires passing around large amounts of state to different functions, and I'm wondering if there is a more space-efficient solution.

  • want to change background of table td on hover

    - by Brad
    I have a webpage that displays a calendar, and I want to change the background-color of any td that has their day number linked, so when I hover over that day, it changes the background-color. I thought this would work: .main-calendar td { width:14%; height:100px; text-align:center; border:1px solid #000; font-size:20px; vertical-align:middle; display:block; } table.main-calendar td a:hover, table.main-calendar td a:visited { display:block; text-decoration:none; background-color:red; color:#fff; } table.main-calendar td a:link { display:block; text-decoration:none; background-color:green; color:#fff; } Any help is appreciated.

  • Sharepoint Workflow doesn't trigger after created/edited tickets

    - by Brad Johnson
    I have a workflow created in Sharepoint designer that works fine when manually triggered. I want it to trigger when a new ticket is created and when an existing ticket is edited. I have tried everything, but it makes no sense that it works when manually triggered, but does not appear to trigger when tickets are created/modified. Any help would be appreciated.

  • Unit Testing a rails 2.3.5 plugin

    - by brad
    I'm writing a new plugin for a rails 2.3.5 app. I've included an app directory (which makes it an engine) so i can easily load some extra routes. Not sure if that affects anything. Anyway, in the test directory i have two files: test_helper.rb and my_plugin_test.rb These files were generated automatically using script/generate plugin my_plugin When I go to vendor/plugins/my_plugin directory and run rake test they don't seem to run. I get the following console output: (in /Users/me/Repos/my_app/source/trunk/vendor/plugins/my_plugin) /Users/me/.rvm/rubies/jruby-1.4.0/bin/jruby -I"lib:lib:test" "/Users/me/.rvm/gems/jruby-1.4.0/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/my_plugin_test.rb" So it obviously sees my test file, but none of the tests inside get run, I just get back to my console prompt. What am I missing here? I figured the generated code would work out of the box Here are the two files test_helper.rb require 'rubygems' require 'active_support' require 'active_support/test_case' my_plugin_test.rb require 'test_helper' class MyPluginTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "Factories are supported" do assert_not_nil Factory end end File structure vendor - plugins - my_plugin - app - config - routes.rb - generators - my_plugin - some generator files.rb - lib - my_plugin.rb - my_plugin - my_plugin_lib_file.rb - rails - init.rb - Rakefile - tasks - my_plugin_tasks.rake - test - test_helper.rb - my_plugin_test.rb

  • Hashing a python method to regenerate output when method is modified

    - by Seth Johnson
    I have a python method that has a deterministic result. It takes a long time to run and generates a large output: def time_consuming_method(): # lots_of_computing_time to come up with the_result return the_result I modify time_consuming_method from time to time, but I would like to avoid having it run again while it's unchanged. [Time_consuming_method only depends on functions that are immutable for the purposes considered here; i.e. it might have functions from Python libraries but not from other pieces of my code that I'd change.] The solution that suggests itself to me is to cache the output and also cache some "hash" of the function. If the hash changes, the function will have been modified, and we have to re-generate the output. Is this possible or a ridiculous idea? If this isn't a terrible idea, is the best implementation to write f = """ def ridiculous_method(): a = # # lots_of_computing_time return a """ , use the hashlib module to compute a hash for f, and use compile or eval to run it as code?
