I created a controller names. I have a model that contains a names of boys and girls (gender=0 for boys, 1 for girls).
If I set to URL the address localhost:3000/names, so will be rendered the view index.html.erb. In this view is an overview of data that are stored in database.
I am trying to edit it - I want to have on the address localhost:3000/names a crossing - here will be 2 links - BOYS and GIRLS. And after click on one of these links I would like to go on the address localhost:3000/names/girls (or boys) and here I would like to have an overview of data from database...
I am newbie still and I don't know, how to realize it... mainly how to edit my routes.rb - I would like to ask you about a help, how to do it...
Thank you in advance
So you want a names_controller with actions boys and girls, and you want routes to those?
How about something like this:
resources(:names) do
collection do
get :boys
get :girls
end
end
Routes collection is documented here.

my problem is the following. I'm currently making a blog-page with get-page, get-resources, form-it, and wayfinder. This question requires a decent amount of knowledge about Modx and snippits. I've got the page numberin and all working and i've got a template page with all my calls in it (called weblogTemplate). This template has the following wayfinder call in it :
[[!getResources? &parents=`5` &limit=`5` &tpl=`blogPost`]]
[[!getPage?
&elementClass=`modSnippet`
&element=`getResources`
&parents=`4`
&depth=`2`
&limit=`5`
&pageNavOuterTpl=`[[+first]][[+prev]][[+pages]][[+next]][[+last]]`
&pageVarKey=`page`
&pageFirstTpl=`<li class="controlFirst"><a[[+classes]][[+title]] href="[[+href]]">Eerste pagina</a></li>`
&pageLastTpl=`<li class="controlLast"><a[[+classes]][[+title]] href="[[+href]]">Laatste pagina</a></li>`
&pagePrevTpl=`<li class="controlPrev"><a[[+classes]][[+title]] href="[[+href]]"><<</a></li>`
&pageNextTpl=`<li class="controlNext"><a[[+classes]][[+title]] href="[[+href]]">>></a></li>`
&includeTVs=`1`
&includeContent=`1`
&tpl=`blogListPost`
]]
as you can see the parent is set here to id number 5. This is fine for the homepage but any child page connected in the blog page also uses the same template and so would also have the same menu as the parent. You could use a fix to simply create 1 template for a page and keep using a different getResource call but keep in mind that it is a blog im making, new pages keep getting added. The user can't (, and wouldn't even understand to) make a template and edit any code. A solution i thought of would be to make the parent id dynamic, so it adjust to whatever page it is currently on. So for example if it was on the page with id number 12 it would make the parent call set to 12 and so show all the content under id number 12. If anyone has any ideas / thoughts / solutions i would be very grateful to hear them.
(a link about wayfinder that i used.)
The best solution would be to use two templates - one for main and one for the blog pages and use in blog templates:
&parents=`[[*id]]`
The problem with the user solveds by setting default_template in the system settings.
This worked for me:
[[!getPage?
&elementClass=`modSnippet`
&element=`getResources`
&parents=`[[*id]]`
&depth=`0`
&limit=`10`
&pageNavOuterTpl=`[[+first]][[+prev]][[+pages]][[+next]][[+last]]`
&pageVarKey=`page`
&pageFirstTpl=`<li class="controlFirst"><a[[+classes]][[+title]] href="[[+href]]">Eerste pagina</a></li>`
&pageLastTpl=`<li class="controlLast"><a[[+classes]][[+title]] href="[[+href]]">Laatste pagina</a></li>`
&pagePrevTpl=`<li class="controlPrev"><a[[+classes]][[+title]] href="[[+href]]"><<</a></li>`
&pageNextTpl=`<li class="controlNext"><a[[+classes]][[+title]] href="[[+href]]">>></a></li>`
&includeTVs=`1`
&includeContent=`1`
&tpl=`blogListPost`
]]
Thanks to Vasis for the provided help.
I'm having some trouble making some graph calls with Koala.
Graph calls:
#graph_data = #api.get_object("me/books")
#account_data = #api.get_connections("me","accounts")
I have a do loop in my callback.html.erb that shows a table which displays the name of the user's favorite books.
(had to remove the html tags)
#graph.data.each do |data|
data["name"]
end
This code is fine, i get a table with all the book names.
The problem occurs when i want to display the #account_data object, this is supposed to hold the information of all the pages the user is an admin of.
I am expecting a table with the names of all the pages the user is subscribed to.
#account_data should have exactly two array elements since i am admin for two pages.
My understanding is that i should be getting an object that looks like this:
[{field1=>val1,field2=>val2,....}, {field1=>val1,field2=>val2,....}]
I tried using the Graph call #api.get_object("me/accounts") but same problem - blank screen.
Thanks in advance.
I have two unrelated models, say Person and Building. When the app receives a url like www.mysite.com/JohnDoe/EmpireState I would like to show properties of the Person with the name johnDoe, and the same for the building with the name EmpireState.
I'm confused as to the routing part specifically. I'm unsure if I need to create a pages controller that can return the objects from the database. How should I go about doing this?
Am hoping for something like below?
match ':user_name/:building_name', :controller => pages
If those two are not related, you shouldn't do it that way. If they ARE related, we call that nested resources.
Example:
resources :projecs do
resources :tasks
end
Sample URL: "/projects/12/tasks/1281"
Edit:
If they are NOT related (taken from my comment):
In your BuildingsController you can fetch the parent informations too. If you use the match route in your question, you'll have params[:user_name] AND params[:building_name] available and can fetch anything you want with them...
Building.find_by_name(params[:building_name]) # return all Buildings based on URL param
Doing the following routes configuration:
resources :cadeiras do
resources :professores
end
resources :cadeiras do
resources :fichas
end
resources :fichas do
resources :exercicios
end
will generate me 2 different links to the same controller and action, running rake routes ill get something like:
fichas GET /fichas(.:format) {:action=>"index", :controller=>"fichas"}
cadeira_fichas GET /cadeiras/:cadeira_id/fichas(.:format) {:action=>"index", :controller=>"fichas"}
The first action will reference all the 'fichas' while the second on is referencing only 'fichas' from 'cadeiras' how is it possible to distinguish the two actions?
I would like to avoid three level nesting problems as described here :http://weblog.jamisbuck.org/2007/2/5/nesting-resources
Thank you for your time
If I understand your question correctly, the answer is "you don't distinguish them" :
The exact same action is executed from the controller, rendering the exact same view. The difference is the collection of 'fichas' that get sent to the view:
- in the first case, all fichas are available in the view
- in the second case, only the 'fichas' related to the 'cadeira' are available in the view (e.g. /cadeira/1/fichas will display only the 'fichas' related to the 'cadeira' with id 1)
To determine which records to show (e.g.) in an index view, you can do something like this:
unless cadeira_id = params[:cadeira_id]
#fichas = Ficha.all
else
#fichas = Cadeira.find(cadeira_id).fichas
end
The rest is up to the view: it should render fichas the same way, you just chose which records are actually made available to it.
I am making something that's like that autocomplete tags field for the posts on stackoverflow.com
I want to make it so that when you make a blog post, you can tag it with words in a database, similar to SO.
For the posts, it belongs_to_and_has_many tags
For the tags, it belongs_to_and_has_many posts
However it is a problem for me to do it on the same page because #post would be nil.
How can I implement this?
(If someone can give me the code for the stackoverflow ask question page that would be AWESOME)
I think the problem here is that it seems like you are asking two different questions. Please correct me if I'm wrong on this.
The first question is how you would implement the autocomplete feature to allow users to easily select from a pre-populated list of tags. To answer this, you might refer to spncrgr's answer above.
The second question is how to deal with associating these retrieved tags to the current post. For this you can add additional javascript functionality to your autocomplete solution. When a user selects which tag they want from the autocomplete field, you can do like StackOverflow does and add the tag to a list of tags in a single text field. These can be either space or comma delimited. When you submit the form to create the new post, you can parse this field into it's separate tags:
tags = params[:tags].split(' ')
You can then associate these tags to the model in the Post#create action.
This may not help you at all (or you may have already seen it), but here's a link to a Railscasts' episode on auto-complete:
http://railscasts.com/episodes/102-auto-complete-association
I know it helped me when trying to do something similar.
HTH
It looks for me like you want to generate tags automatically.
You could create
class Post
before_save :create_tags
private
def create_tags
# get your tags somehow
self.tags << Tag.new(:text=>"...")
end
end
method in models/post.rb and build them there.
If you want to search among existing tags for your auto-suggest, you should have it match from Tag.all, as that won't be nil, just as you would collect a group of objects in a select drop down. Not sure about the code for auto-complete, but the tags should be in the Tag table.
