I'm trying to get a "What's new" section working in my Rails app that takes into account new records created for various tables that don't share any relationships. The one thing they do have in common is that they all have a created_at field, which I'm going to use to determine if they're indeed "new" and then I'm wanting to sort the results by that common field. I tried doing this with Sunspot, but I couldn't figure out how to make use of the the result set returned from the Sunspot search...
For instance in my Uploads and Article models I have:
searchable do
time :created_at
end
and in my search action I'll do this:
#updates = Sunspot.search(Upload,Article) do
with(:created_at).greater_than(1.hour.ago)
end
Which does seem to return something, if I do an #updates.total it returns the number of records I was expecting to find. Beyond this I'm not sure how to actually make use of the records. What I'd like to do is send #updates to a view and determine the model type of each record and then proceed to print out the relevant information, i.e names, descriptions, parent/child record information (for instance upload.user.username).
I might be going at this all wrong, perhaps there's a better option than sunspot for the simple search I'm attempting to perform?
Refer readme for details of how to use the search results. The method you are looking for is "results", which will give you first 30 results, by default:
#updates.results # array of first 30 results

Good day, hope everything's well.
I'm trying to find the value of tax_ids (Many2many field) inside the account.move.line model but i can't seems to find anything. I already access the psql of the database but i cant find tax_ids too.
I accessed that account.move.line model with ORM like this :
def _post(self, soft=True):
for move in self:
....
account_move_line = self.env['account.move.line'].search([('id', '=', int(move.id))])
print(account_move_line.tax_ids) #this find nothing
could someone please elaborate how is it possible to access id of the tax that applied to, in this case, an invoice line record?
Edit : Sometimes this ORM fetching the ID and sometimes it doesn't. But most likely it's not fetching.

tax_ids in account.move.line model is a Many2Many field, which is stored separately as another table in the database. This kind of relation field mostly be named something like this (main_table)_(related_table)_rel (ignore the parentheses). For example, this particular case's table is account_move_line_account_tax_rel since its main table is account_move_line and the related table for that specific field is account_tax. Inside the relation table, you will almost always find 2 fields mapping both ids together. For this case, it is going to be account_move_line_id and account_tax_id.

Accessing a field via ORM always works as you intended if it is implemented correctly. In your code, you are searching account_move_line by id but you are trying to search it with move.id, which I assume it is account_move since you got the data sometimes. If you can access the lines that you want correctly, you will see that account_move_line.tax_ids will always give you the correct tax_ids. From what your code looks, I think you are trying to search the lines by its account_move. Therefore, your domain should be [('move_id', '=', int(move.id))] instead.
I'm working on a task where I have to define a function that attaches something to a column in my DB, however I'm quite new and despite looking at the ActiveRecord documentation I don't appear to be able to grab the column I'm looking for.
For example, I have a table with many columns including 'State' and 'Phase', I was able to grab state with the following code:
CaseFileStatus.where(state: case_file.state).first
However I can't somehow manage to grab the 'Phase' column now, as shown below.
CaseFileStatus.where(state: "case_file.phase")
CaseFileStatus Load (2.5ms) SELECT "case_file_statuses".* FROM "case_file_statuses" WHERE "case_file_statuses"."state" = $1 [["state", "case_file.phase"]]
=> []
I'm sure it's a super basic error, but how should I be structuring this query?
If you need to query records based on the phase column, you should do something like this:
CaseFileStatus.where(phase: case_file.phase)
I have a form for submitting an order, and I need an autocomplete field that searches across three attributes in the associated customer model: first name, last name, and customer_number (as opposed to customer.id). I know about the rails3-jquery-autocomplete gem found here http://github.com/crowdint/rails3-jquery-autocomplete, and got it working well, but a question has occurred to me -- is there a more efficient way to make the autocomplete work without having to query the db every time?
The other solution that occurred to me is to create a new indexed attribute in the customer model -- call it autocomplete_data. Whenever a new customer is added via the usual new customer form, an :after_create callback could populate the field. Would this speed up the performance? Or am I overthinking it?
UPDATE
I'm embarassed to say that I just didn't search hard enough the first time around -- I think this actually answers my question:
Rails: Efficiently searching by both firstname and surname
(I tried posting this to the CFWheels Google Group (twice), but for some reason my message never appears. Is that list moderated?)
Here's my problem: I'm working on a social networking app in CF on Wheels, not too dissimilar from the one we're all familiar with in Chris Peters's awesome tutorials. In mine, though, I'm required to display the most recent status message in the user directory. I've got a User model with hasMany("statuses") and a Status model with belongsTo("user"). So here's the code I started with:
users = model("user").findAll(include="userprofile, statuses");
This of course returns one record for every status message in the statuses table. Massive overkill. So next I try:
users = model("user").findAll(include="userprofile, statuses", group="users.id");
Getting closer, but now we're getting the first status record for each user (the lowest status.id), when I want to select for the most recent status. I think in straight SQL I would use a subquery to reorder the statuses first, but that's not available to me in the Wheels ORM. So is there another clean way to achieve this, or will I have to drag a huge query result or object the statuses into my CFML and then filter them out while I loop?
You can grab the most recent status using a calculated property:
// models/User.cfc
function init() {
property(
name="mostRecentStatusMessage",
sql="SELECT message FROM statuses WHERE userid = users.id ORDER BY createdat DESC LIMIT 1,1"
);
}
Of course, the syntax of the SELECT statement will depend on your RDBMS, but that should get you started.
The downside is that you'll need to create a calculated property for each column that you need available in your query.
The other option is to create a method in your model and write custom SQL in <cfquery> tags. That way is perfectly valid as well.
I don't know your exact DB schema, but shouldn't your findAll() look more like something such as this:
statuses = model("status").findAll(include="userprofile(user)", where="userid = users.id");
That should get all statuses from a specific user...or is it that you need it for all users? I'm finding your question a little tricky to work out. What is it you're exactly trying to get returned?
I want to search in multiple fields in Solr.
(In know the concept of the copy-fields and I know the (e)dismax search handler.)
So I have an orderd list of fields, I want the terms to be searched against.
1.) SKU
2.) Name
3.) Description
4.) Summary
and so on.
Now, when the query matches a term, let's say in the SKU field, I want this match and no further searches in the proceeding fields.
Only, if there are NO matches at all in the first field (SKU field), the second field (in this case "name") should be used and so on.
Is this possible with Solr?
Do I have to implement my own Lucene Search Handler for this?
Any advice is welcome!
Thank you,
Bernhard
I think your case requires executing 4 different searches. If you implement you very own SearchHandler you could avoid penalty of search result accumulation in 4 different request. Which means, you would send one query, and custom SearchHandler would execute 4 searches and prepare one result set.
If my guess is right you want to rank the results based on the order of the fields. If so then you can just use standard query like
q=sku:(query)^4 OR name:(query)^3 OR description:(query)^2 OR summary:(query)
this will rank the results by the order of the fields.
Hope is helps.
