I am trying to chain a calendaer_date_select to a select field, so the select list is filtered by the choosen date. I have followed the instructions as described here
I have in the activescaffold config:
config.columns[:order_date].form_ui = :calendar_date_select
config.columns[:order_date].options = {:update_column => :sale}
config.columns[:sale].form_ui = :select
... and in the helper:
def options_for_association_conditions(association)
if association.name == :sale
{'sales.order_date' => #record.order_date}
else
super
end
end
The problem is that picking a date from the javascript widget thingy
doesn't trigger the select to refresh. However if I type in the date
then it does. Any ideas?
This was a bug with ActiveScaffold that was fixed this morning. So cloning the repository again will solve your problems.
For the record, the method ActiveScaffold uses to watch for changes doesn't catch the way that Calendar Date Select sets the field. ActiveScaffold watches for change events on fields for column updates. Change events are triggered by a modification in a fields value between the time it gains and loses focus. Calendar Date Select modifies the value without giving or removing focus to the field.
If you don't feel like updating your plugins, you could hack it together your self by doing the following:
config.columns[:order_date].options = {:update_column => :sale}
to
config.columns[:order_date].options = {:update_column => :sale,
:before_show => 'this.focus()', :onchange => 'this.blur()'}

I need to get the records only included on time range using default created_at Rails field. No matters the day was created.
I have this:
#start_time = test.start_time.strftime("%I:%M%p")
#end_time test.end_time.strftime("%I:%M%p")
#websites = device.websites.where(:created_at => #start_time..#end_time)
I was searching for something like this:
#websites = device.websites.where(:created_at::time => #start_time..#end_time)
This generate this SQL sentence without results.
SELECT DISTINCT `websites`.* FROM `websites` WHERE `websites`.`device_id` = 2 AND (`websites`.`created_at` BETWEEN '16:10:00' AND '21:10:00')
But if I add time function to created_at field, works fine.
SELECT DISTINCT `websites`.* FROM `websites` WHERE `websites`.`device_id` = 2 AND (time(`websites`.`created_at`) BETWEEN '16:10:00' AND '21:10:00')
How is the best Rails way to do this ?
Rails automatically converts the time objects to the format that your database requires, so there is no need for strftime. You should be able to do it like this:
#websites = device.websites.where(:created_at => test.start_time..test.end_time)
I have a model called Story that I'm trying to order by the created_at date. Since I've hosted my app on Heroku, which uses Postgresql, I have the following in my controller:
#stories = Story.find( :all, :order => "DATE(created_at) DESC" , :limit => 11)
I would expect this to give the first 11 of my stories, ordered by the creation date, with the newest story first.
Unfortunately, this doesn't work. Most of the stories return ordered correctly, but the first two are flipped. That is, the latest story appears second in the list.
Why would this be? I have a sneaky suspicion that my results aren't ordered at all or are being ordered on the wrong column (maybe id?) and that until now it just happened to be ordered like I expected when displayed on my index page. How can I get it to order as I expect it to?
In case anyone cares, the index view is simply displaying the stories, in order. That is (HAML):
- #stories.each do |story|
= render :partial => "event", :locals => { :event => story }
EDIT
I am suspicious that the created_at is a datetime column and the DATE(...) function disregards the time portion. So it returns the elements created on the same date in a random order. Since the first two stories were created on the same day, but several hours apart, which would explain why they seem to be 'reversed'. If this is the case, what would be the correct syntax to order by both date and time?
I believe you want:
#stories = Story.find(:all, :order => "created_at DESC" , :limit => 11)
Update for Rails 3+:
#stories = Story.order(created_at: :desc).limit(11)
If you are using Rails 3, I would also encourage you to use the cool new query syntax which would be:
#stories = Story.order('created_at DESC').limit(11)

I use the gem rails3-jquery-autocomplete for the autocomplete searching of items in my database. The autocomplete is working fine, but I would need to add another condition to the generated query.
If I start to write a searched string, then is generated following query:
SELECT persons.id, persons.name FROM "persons" WHERE (LOWER(persons.name) ILIKE 'jo%') ORDER BY persons.name ASC LIMIT 10
This returns me all rows, where the name starts at jo.
But how could I search all persons, which name starts at jo and simultaneously, for example, the column active_person=1?
Is there any helper for this purpose or something like that?
Thank you
If I understood the context correctly, then active_person is a boolean that indicates whether the user is active or not.
If this behavior is desirable most of time - that you search for users/people that are only active then you could include a default_scope in your Person model like this:
class Person < ActiveRecord::Base
default_scope where(:active_person => 1)
end
This way any query that is ever generated will be also checking that active_person = 1
More on default scopes here: http://apidock.com/rails/ActiveRecord/Base/default_scope/class
I understand that #Andrei 's answer is correct, but its not what I was looking for. I guess its same for #user984621 too. What I was looking for is I want to add an extra condition to the query.
By reading this https://github.com/crowdint/rails3-jquery-autocomplete/blob/master/lib/rails3-jquery-autocomplete/orm/active_record.rb
I found that rails autocomplete supports additional conditions, you just have to pass another parameter to the default usage, like this
autocomplete :user, :name, :where => { :role => 'employee'}
instead of this
autocomplete :user, :name
Change WHERE (LOWER(persons.name) ILIKE 'jo%') to WHERE (LOWER(persons.name) ILIKE 'jo%') AND active_person = 1
You can chain together loads of clauses with ANDs and OR in that way.
Note that this is really a question about SQL: your title and tags are a bit misleading.
I have a Ruby on Rails site that uses thinking sphinx for searching a postgres database.
One of the fields in a table I am searching on is a boolean.
I'd like to be able to match on that boolean when a certain keyword is used in the search query.
To fully explain with an example:
My site is for people who develop their own black and white film.
I have a recipe table where people describe how they develop a film. That table has a boolean column called "stand_developed" (a method of developing film).
I'd like to return results where that field is true when the user searches for the word "stand".
I've been through the sphinx docs and not really found if it's possible.
I guess I could hack something inside my controller method by parsing the query terms and adding a condition but is there a cleaner way of doing it?
This is what I've done as far as searching on boolean fields using ThinkingSphinx. Pass stand_developed as a URL parameter along with your query_string in the following ways:
URL for a general query without search on stand_developed will be http://yoursite.com/search?q=your_query_string
URL for query with stand_developed == TRUE will be http://yoursite.com/search?q=your_query_string&stand_developed=1
URL for query with stand_developed == FALSE will be http://yoursite.com/search?q=your_query_string&stand_developed=0
Then, in your controller, you would do this:
if params[:stand_developed] && params[:stand_developed].to_i == 1
# perform query search with stand_developed == true
#search_results = YourModel.search(params[:q], :with => {:stand_developed => true})
elsif params[:stand_developed] && params[:stand_developed].to_i == 0
# perform query search with stand_developed == false
#search_results = YourModel.search(params[:q], :with => {:stand_developed => false})
else
# perform general query search
#search_results = YourModel.search(params[:q])
end
You could have just tested if params[:search] included the text 'stand' then done the searching from there. You don't need an extra column in your table, that's just overhead that's not needed.
if params[:search].downcase.include?('stand')
Model.search params[:search], :with => {:stand_developed => true}
else
Model.search params[:search]
end
I've come up with a solution to this now.
I tried the "hack" I mentioned in my question - parsing the word "stand" and searching for it explicitly (a variation on the answer from Paul Davis) but it didn't work very well.
I didn't explain this in my question (didn't realise the full implications at the time I asked) but I need it to also match if the user used the word "stand" in their recipe description too.
So, I tried to get sphinx to add a condition along the lines of "if stand_developed is true or notes contains 'stand'" but I couldn't seem to find the right syntax for that.
It also had to deal with any other search text too.
In the end I added an extra column to my recipe table called "search_tags" and I add the word "stand" into it if the user selects "stand_developed" when adding a recipe.
I then get Sphinx to index that field as well as my other fields and it all works perfectly.
I have Widget.title, Widget.publish_ at, and Widget.unpublish_ at. It's a rails app with thinking_sphinx running, indexing once a night. I want to find all Widgets that have 'foo' in the title, and are published (publish _at < Time.now, unpublish _at > Time.now).
To get pagination to work properly, I really want to do this in a sphinx query. I have
'has :publish_at, :unpublish_at' to get the attributes, but what's the syntax for 'Widget.search("foo #publish_ at > #{Time.now}",:match _mode=>:extended'? Is this even possible?
Yep, easily possible, just make sure you're covering the times in your indexes:
class Widget < ActiveRecord::Base
define_index do
indexes title
has publish_at
has unpublish_at
...
end
To pull it based purely off the dates, a small amount of trickery is required due to sphinx requiring a bounded range (x..y as opposed to x>=y). The use of min/max value is very inelegant, but I'm not aware of a good way around it at the moment.
min_time = Time.now.advance(:years => -10)
max_time = Time.now.advance(:years => 10)
title = "foo"
Widget.search title, :with => {:publish_at => min_time..Time.now, :unpublish_at => Time.now..max_time}
I haven't used sphinx with rails yet.
But this is possible by the Sphinx API.
What you need to do is to set a datetime attribute at your sphinx.conf.
And don't forget to use UNIX_TIMESTAMP(publish_at), UNIX_TIMESTAMP(unpublish_at) at your index select.
