• Paperclip generating wrong URLs in Heroku

  - by Tony

  Paperclip is generating wrong URLs in Heroku. I have an Audio model which has a mp3 field as follows: class Audio < ActiveRecord::Base has_attached_file :mp3, :storage => :s3, :s3_credentials => S3_CREDENTIALS, :bucket => S3_CREDENTIALS[:bucket], :path => ":rails_root/public/system/:attachment/:id/:style/:filename", :url => "/system/:attachment/:id/:style/:filename" I am calling audio.mp3.url from a controller, and it returns http://s3.amazonaws.com/MyApp/audios/mp3s//original/96a9ae89302fdf8462ee05eb829f2e17578b144e20120908-2-11f61zr.mp3?1347135050 instead of http://s3.amazonaws.com/MyApp/audios/mp3s/000/000/004/original/96a9ae89302fdf8462ee05eb829f2e17578b144e20120908-2-11f61zr.mp3?1347135050 (which works) Why is it missing the '000/000/004' part of the route? The same model is generating the right URL when used in a view. Any help? I am using paperclip 3.2.0 and Rails 3.1.8. Any help?

• Using non-Railsy route to prepopulate a form

  - by user94154

  I have many instances of a Rails model, Post. When viewing an individual post, I'd like to create a form to create a child of Post called Comment. I'd like to prepopulate this form with a hidden tag that contains the post_id which is the foreign key in Comment. The Railsy way to do this is to create a fancy-ish route such as: /comments/new/post/:post_id However, this gunks up the routes file and doesn't leave much flexibility. Let's say I want to create a link somewhere else that prepopulates a different attribute of the form...then I'd have to add another route for this. So I think I'm going to create urls like this on /posts/show/:id: /comments/new?comment[post_id]=<%= @post.id %> This way I can add any other attributes as I need. I know the plus side associated with this, now what are the downsides?

• Understanding Eager Loading & How to use it? (specific issue)

  - by Elliot

  I have the following relation in my rails app: genre - has many - authors authors - belong to genre and has many books books - belongs to authors and belongs to users (users can add books to the db) in my controller I have: @books=current_user.books(:include => [:author => :genre], :order => 'books.created_at DESC')--- -- In my controller I used to have: @authors = Author.All @genres = Genre.All etc. -- In my view I have @genres.each do |genre| @authors.each do |author| if author.genre_id == genre.id stuff end end end Now that I'm using eager loading, I can't imagine this is the best way to do this (nor does it work as I don't have the @ variables) - I was wondering if anyone could shed some light on how to approach this?

• Set a session hash outside of RoR program?

  - by Sindri Guðmundsson

  Hi, I have had my new rails program up for a few days now. I'm running it on Ubuntu 10.4 with apache2 in another location than the website it's made for (it's a standalone database application for physiotherapists). The people I made it for now want me to deploy it to the public part of their website, only with one change. Those who open it via the link in the public-part should not be able to click one button! I was thinking of doing something like this in my view: <% if session[:inside]%> <%=button_to 'Sækja mælitæki', @link_to_mt%> <%end%> How could I set session[:inside] only to true if the program was started from within the private part of the webpage? I thought of creating two new actions, the other would set session[:inside] to true and the other to false, but that seems to me like a security risk, is it not? BR, Sindri

• ActiveRecord date format

  - by Mongus Pong

  I've run into a spot of bother with date formats in our Rails application. I have a date field in our view which I want to be formatted as dd/mm/yy. This is how the user will expect to enter their dates, and the datepicker control uses this format. However, Active Record seems to be expecting mm/dd/yy. If I enter 01/03/2010, this gets put in as 03 January 2010. If I enter 25/03/2010, this gets put in a null. How do I get ActiveRecord to expect Her Majesties date format?

• ActiveRecord find all parents that have associated children

  - by brad

  I don't know why I can't figure this out, I think it should be fairly simple. I have two models (see below). I'm trying to come up with a named scope for SupplierCategory that would find all SupplierCategory(s) (including :suppliers) who's associated Supplier(s) are not empty. I tried a straight up join, named_scope :with_suppliers, :joins => :suppliers which gives me only categories with suppliers, but it gives me each category listed separately, so if a category has 2 suppliers, i get the category twice in the returned array: Currently I'm using: named_scope :with_suppliers, :include => :suppliers and then in my view I'm using: <%= render :partial => 'category', :collection => @categories.find_all{|c| !c.suppliers.empty? } %> Not exactly eloquent but illustrates what I'm trying to achieve. Class Definitions class SupplierCategory < AR has_many :suppliers, :order => "name" end class Supplier < AR belongs_to :supplier end

• fields_for to stop pluralizing.

  - by Dmitriy Likhten

  I have a fields_for tag, where I specify the prefix (lets say for some good reasons), and this is supposed to represent a one-to-one relationship. I am trying to represent a relationship widget has_many thingamagigs thingamagig has_one whatchamacallit The field_for code is: fields_for "widgt[thingamagigs_attributes][][whatchamacallit_attributes]", thingamagig.whatchamacallit do |x| which generates names (wrongly): widget[thingamagigs_attributes][][whatchamacallit_attributes][][value] The better solution would be t.fields_for :whatchamacallit do |x| where t = fields_for the thingamagig... However if I do that, the following names are generated widgt[thingamagigs_attributes][whatchamacallit_attributes][] which is completely wrong as all other fields for a thingamagig is... widgt[thingamagigs_attributes][][name] So in all cases I am screwed. The original field_for using a string cannot be used with accepts_nested_attributes_for :whatchamacallit since whatchamacallit is a singular relationship and an object is expected not an array. The second fields_for will simply not work because rails cannot parse the params object correctly. Is there a way to tell the first forms_for to not add the [] after [whatchamacallit_attributes] in all field names?

• How to reduce latency of data sent through a REST api

  - by Sid

  I have an application which obtains data in JSON format from one of our other servers. The problem I am facing is, there is is significant delay when when requesting for this information. Since a lot of data is passed (approx 1000 records per request where each record is pretty huge) is there a way that compression would help reducing the speed. If so which compression scheme would you recommend. I read on another thread that they pattern of data also matters a lot on they type of compression that needs to be used. The pattern of data is consistent and resembles the following :desc=>some_description :url=>some_url :content=>some_content :score=>some_score :more_attributes=>more_data Can someone recommend a solution to how I could reduce this delay. They delay is approx 6-8 seconds. I'm using Ruby on Rails to develop this application and the server providing the data uses Python for the most part.

• Running Test framework as part of application

  - by VP

  Hi, I would like to know if it is possible in rails to run some test cases through my application. I mean, i want show the test results to users. So i was thinking to be able to call my tests through a controller and put the tests output in a dialog. Imagine that i'm doing an application where before to apply a rule, i want to run some validation tests. I could write methods in my rule model to do it, but i would like to use something like shoulda or any other kind of DSL where the "fixture" would be a record itself. Any tip or idea?

• Nested form child only updates if parent changes.

  - by chap

  In this video (10 sec) you can see that the nested attribute is only updated if it's parent model is changed. Using rails 3.0.0.beta and full project is on github.

• Trying to get paperclip to refresh or reprocess..

  - by Trip

  I have over time, changed the size for thumbs of the class Deal. Through these changes, users were uploading to the site, so there are few people who have different sized thumbs. I wanted to reprocress or refresh these, so I went to into my root and typed: $ rake paperclip:refresh class=Deal Did nothing for the thumb sizes.. Then I : irb Deal.find(987).reprocess! Returned this : NoMethodError: undefined method `reprocess!' for #<Deal:0xb68a0988> from /data/HQ_Channel/releases/20100607130346/vendor/rails/activerecord/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):7 My deal class is this : => Deal(id: integer, organization_id: integer, deal: string, value: string, what: string, description: string, image_file_name: string, image_content_type: string, image_file_size: integer, image_updated_at: datetime, created_at: datetime, updated_at: datetime, deal_image_file_name: string, deal_image_content_type: string, deal_image_file_size: integer, deal_image_uploaded_at: datetime) What can i do to have it reprocess the original to make the thumb the correct size in the current thumb size params?

• Multiple row insertion in a faster way

  - by Cyborgo

  Hi, I am using rails and I am trying to insert new rows into the table. The data comes from a text file and I created hash with one of the attribute as key. Then I find all the keys that are currently not in the table. Then I need to insert all of them into the table with all the attributes that I saved in hash. newvals.each{ |x| author = Author.create(:first => x, :second => hash[x][0], :third => hash[x][1]) author.save } This has lot of overhead as it makes an SQL update one at time. The newals array is usually quite big around the size of 20-30k. I know create can insert multiple objects at once, but I cant seem to figure out how. Is there any way to get this done. Thanks.

• Internet Explorer 8 doesn't finish downloading the page!

  - by Eric the Red

  I'm currently finishing up testing a new Ruby on Rails app. Just recently, some of the pages do not seem to finish downloading in IE8. In FireFox, Chrome and Safari, everything works perfectly. The pages all validate successfully using the W3C validator. When I view the page source in IE8, the page has been chopped off around 75% of the size it should be. IE8 claims the page is finished loading, and doesn't give any errors, but of course the page isn't rendering properly. Has anyone seen this before? I'd really appreciate any help.

• $.ajax + authentication + `@` in username

  - by Koning Baard XIV

  I am creating a web app which uses jQuery to authenticate: $.ajax({ url: "/session/create?format=json", type: "GET", dataType: "json", cache: false, username: $("#signin-email").val(), password: $("#signin-password").val(), success: function(data) { if(data.success) { success = true; } } }); The problem is that the code only makes the AJAX-request when the username does not include things like an @, which is required in my app. Can anyone help me with how I can do this? I do not mind changing the back-end a little bit, but requiring users to have an @-less email is not an option. Oh, my back-end is a Ruby-on-Rails app

• Implementing an Online Waiting Room

  - by saalon

  My organization is building a new version of our ticketing site and is looking for the best way to build an online waiting room when the number of users in our purchase path exceeds a certain limit. The best version of this queue would let new users in after existing users have either completed their purchase or have exceeded a timeout limit after entering the path. I'm trying to get an idea of how this has been implemented by other organizations. Has anyone out there done something similar or have any experience with this? We have some ideas, but I'd like to get a sense of what solutions have been tried and what problems those solutions have run up against. Just to be complete, this site is being built in Ruby on Rails, though I'd love to hear about how people have solved this regardless of platform.

• Updating cached counts in MySQL

  - by phleet

  In order to fix a bug, I have to iterate over all the rows in a table, updating a cached count of children to what its real value should be. The structure of the things in the table form a tree. In rails, the following does what I want: Thing.all.each do |th| Thing.connection.update( " UPDATE #{Thing.quoted_table_name} SET children_count = #{th.children.count} WHERE id = #{th.id} " ) end Is there any way of doing this in a single MySQL query? Alternatively, is there any way of doing this in multiple queries, but in pure MySQL? I want something like UPDATE table_name SET children_count = ( SELECT COUNT(*) FROM table_name AS tbl WHERE tbl.parent_id = table_name.id ) except the above doesn't work (I understand why it doesn't).

• Associate a URL with a resource within my application

  - by Horace Loeb

  When I visit http://my-application.com/posts/1 in my browser, Rails knows I'm looking for the Post with id = 1. How can I get my application to do this internally? I.e., I'd like a function (call it associate_with_resource) that takes a string containing a URL as its input and outputs the associated resource. For example: >> associate_with_resource('http://my-application.com/posts/1') => #<Post id: 1, ... > (I'd like to be able to use associate_with_resource throughout my application though -- not only in the console)

• Does the '#' modifier for cropping images in Paperclip work only for square images?

  - by user3451384

  It is very well documented that you can create square thumbnails with center cropping with Paperclip (4) and Rails (4). I would like to have an image of very specific dimensions (e.g. 200x100) and if input an image of let's say 800x200 it is first resized to 400x100 and then the width (400) is cropped down to 200 pixel from the center (i.e. 100px cut from the right and 100 px cut from the left). I tried with 200x100# and it does not appear to work (i.e. the '#' has no effect). I have found that I could adapt other solutions such as this, but I was wondering if '#' is supposed to work only for cropping to square images, or is a Paperclip bug or I am doing something wrong...

• Proper way to use before_create

  - by ruevaughn

  Pretty basic question here, I need to write a before filter on my Category model, to ensure that the depth never reaches more than 2. Here is what I have so far. app/models/category.rb before_create :check_depth def check_depth self.depth = 1 if depth > 2 end I need it instead of setting depth to 1, just to return a error message, but I can't even get this current setup to work, I get the error undefined method `>' for nil:NilClass So, instead of setting the depth to one like I'm trying to do how would I send an error instead? And any help getting the current function working for informational purposes? Thanks in advance

• Thick models Vs. Business Logic, Where do you draw the distinction?

  - by TokenMacGuy

  Today I got into a heated debate with another developer at my organization about where and how to add methods to database mapped classes. We use sqlalchemy, and a major part of the existing code base in our database models is little more than a bag of mapped properties with a class name, a nearly mechanical translation from database tables to python objects. In the argument, my position was that that the primary value of using an ORM was that you can attach low level behaviors and algorithms to the mapped classes. Models are classes first, and secondarily persistent (they could be persistent using xml in a filesystem, you don't need to care). His view was that any behavior at all is "business logic", and necessarily belongs anywhere but in the persistent model, which are to be used for database persistence only. I certainly do think that there is a distinction between what is business logic, and should be separated, since it has some isolation from the lower level of how that gets implemented, and domain logic, which I believe is the abstraction provided by the model classes argued about in the previous paragraph, but I'm having a hard time putting my finger on what that is. I have a better sense of what might be the API (which, in our case, is HTTP "ReSTful"), in that users invoke the API with what they want to do, distinct from what they are allowed to do, and how it gets done. tl;dr: What kinds of things can or should go in a method in a mapped class when using an ORM, and what should be left out, to live in another layer of abstraction?

• Models, collections...and then what? Processes?

  - by Dan

  I'm a LAMP-stack dev who's been more on the JavaScript side the last few years and really enjoying the Model + Collection approach to data entities that BackboneJS, etc. uses. It's helped me organize my code in such a way that it is extremely portable, keeping all my properties and methods in the scope (model, collection, etc.) in which they apply. One thing that keeps bugging me though is how to organize the next level up, the 'process layer' as you might call it, that can potentially operate on instances of either models or collections or whatever else. Where should methods like find() (which returns a collection) and create() (which returns a model) reside? I know some people would put a create() in the Collection prototype, but while a collection operates on models I don't think it's exactly right to create them. And while a find() would return a collection I don't think it correct to have that action within the collection prototype itself (it should be a layer up). Can anyone offer some examples of any patterns that employ some kind of OOP-friendly 'process' layer? I'm sorry if this is a fairly well-known discussion but I'm afraid I can't seem to find the terminology to search for.

• Django m2m form appearing fields

  - by dana

  I have a classroom application,and a follow relation. Users can follow each other and can create classrooms.When a user creates a classroom, he can invite only the people that are following him. The Classroom model is a m2m to User table. i have in models. py: class Classroom(models.Model): creator = models.ForeignKey(User) classname = models.CharField(max_length=140, unique = True) date = models.DateTimeField(auto_now=True) open_class = models.BooleanField(default=True) members = models.ManyToManyField(User,related_name="list of invited members") and in models.py of the follow application: class Relations(models.Model): initiated_by = models.ForeignKey(User, editable=False) date_initiated = models.DateTimeField(auto_now=True, editable = False) follow = models.ForeignKey(User, editable = False, related_name = "follow") date_follow = models.DateTimeField(auto_now=True, editable = False) and in views.py of the classroom app: def save_classroom(request, username): if request.method == 'POST': u = User.objects.get(username=username) form = ClassroomForm(request.POST, request.FILES) if form.is_valid(): new_obj = form.save(commit=False) new_obj.creator = request.user r = Relations.objects.filter(initiated_by = request.user) # new_obj.members = new_obj.save() return HttpResponseRedirect('.') else: form = ClassroomForm() return render_to_response('classroom/classroom_form.html', { 'form': form, }, context_instance=RequestContext(request)) i'm using a ModelForm for the classroom form, and the default view, taking in consideration my many to many relation with User table, in the field Members, is a list of all Users in my database. But i only want in that list the users that are in a follow relationship with the logged in user - the one who creates the classroom. How can i do that? Thanks!

• Select those objects whose related objects IDs are *all* in given string

  - by Jannis

  Hi Django people, I want to build a frontend to a recipe database which enables the user to search for a list of recipes which are cookable with the ingredients the user supplies. I have the following models class Ingredient(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) importancy = models.PositiveSmallIntegerField(default=4) […] class Amount(models.Model): recipe = models.ForeignKey('Recipe') ingredient = models.ForeignKey(Ingredient) […] class Rezept(models.Model): name = models.CharField(max_length=100) slug = models.SlugField() instructions = models.TextField() ingredients = models.ManyToManyField(Ingredient, through=Amount) […] and a rawquery which does exactly what I want: It gets all the recipes whose required ingredients are all contained in the list of strings that the user supplies. If he supplies more than necessary, it's fine too. query = "SELECT *, COUNT(amount.zutat_id) AS selected_count_ingredients, (SELECT COUNT(*) FROM amount WHERE amount.recipe_id = amount.id) AS count_ingredients FROM amount LEFT OUTER JOIN amount ON (recipe.id = recipe.recipe_id) WHERE amount.ingredient_id IN (%s) GROUP BY amount.id HAVING count_ingredient=selected_count_ingredient" % ",".join([str(ingredient.id) for ingredient in ingredients]) rezepte = Rezept.objects.raw(query) Now, what I'm looking for is a way that does not rely on .raw() as I would like to do it purely with Django's queryset methods. Additionally, it would be awesome if you guys knew a way of including the ingredient's importancy in the lookup so that a recipe is still shown as a result even though one of its ingredients (that has an importancy of 0) is not supplied by the user.

• Global name not defined error in Django/Python trying to set foreignkey

  - by Mark

  Summary: I define a method createPage within a file called PageTree.py that takes a Source model object and a string. The method tries to generate a Page model object. It tries to set the Page model object's foreignkey to refer to the Source model object which was passed in. This throws a NameError exception! I'm trying to represent a website which is structured like a tree. I define the Django models Page and Source, Page representing a node on the tree and Source representing the contents of the page. (You can probably skip over these, this is a basic tree implementation using doubly linked nodes). class Page(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey("self", related_name="children", null=True); firstChild = models.ForeignKey("self", related_name="origin", null=True); nextSibling = models.ForeignKey("self", related_name="prevSibling", null=True); previousSibling = models.ForeignKey("self", related_name="nxtSibling", null=True); source = models.ForeignKey("Source"); class Source(models.Model): #A source that is non dynamic will be refered to as a static source #Dynamic sources contain locations that are names of functions #Static sources contain locations that are places on disk name = models.CharField(primary_key=True, max_length=50) isDynamic = models.BooleanField() location = models.CharField(max_length=100); I've coded a python program called PageTree.py which allows me to request nodes from the database and manipulate the structure of the tree. Here is the trouble making method: def createPage(pageSource, pageName): page = Page() page.source = pageSource page.name = pageName page.save() return page I'm running this program in a shell through manage.py in Windows 7 manage.py shell from mysite.PageManager.models import Page, Source from mysite.PageManager.PageTree import * ... create someSource = Source(), populate the fields, and save it ... createPage(someSource, "test") ... NameError: global name 'source' is not defined When I type in the function definition for createPage into the shell by hand, the call works without error. This is driving me bonkers and help is appreciated.
