Rails3 CookieOverflow - ruby-on-rails-3

I am getting this error:
ActionDispatch::Cookies::CookieOverflow
In config/application.rb I have:
config.session_store :active_record_store
There is no data being stored in the sessions table.
I am using RubyCAS-client with this code:
https://github.com/zuk/rubycas-client-rails
Am I doing something wrong to have the code stored in the database or is this code not setup to use active record store?

I figured it out, I was doing it in config/application.rb. When I changed it in config/initializers/session_store.rb it worked.
I don't know if this is completely right because I assume config/application.rb is the place it should be?

Enable Impala Impersonation on Superset

Is there a way to make the logged user (on superset) to make the queries on impala?
I tried to enable the "Impersonate the logged on user" option on Databases but with no success because all the queries run on impala with superset user.
I'm trying to achieve the same! This will not completely answer this question since it does not still work but I want to share my research in order to maybe help another soul that is trying to use this instrument outside very basic use cases.
I went deep in the code and I found out that impersonation is not implemented for Impala. So you cannot achieve this from the UI. I found out this PR https://github.com/apache/superset/pull/4699 that for whatever reason was never merged into the codebase and tried to copy&paste code in my Superset version (1.1.0) but it didn't work. Adding some logs I can see that the configuration with the impersonation is updated, but then the actual Impala query is with the user I used to start the process.
As you can imagine, I am a complete noob at this. However I found out that the impersonation thing happens when you create a cursor and there is a constructor parameter in which you can pass the impersonation configuration.
I managed to correctly (at least to my understanding) implement impersonation for the SQL lab part.
In the sql_lab.py class you have to add in the execute_sql_statements method the following lines
with closing(engine.raw_connection()) as conn:
# closing the connection closes the cursor as well
cursor = conn.cursor(**database.cursor_kwargs)
where cursor_kwargs is defined in db_engine_specs/impala.py as the following
#classmethod
def get_configuration_for_impersonation(cls, uri, impersonate_user, username):
logger.info(
'Passing Impala execution_options.cursor_configuration for impersonation')
return {'execution_options': {
'cursor_configuration': {'impala.doas.user': username}}}
#classmethod
def get_cursor_configuration_for_impersonation(cls, uri, impersonate_user,
username):
logger.debug('Passing Impala cursor configuration for impersonation')
return {'configuration': {'impala.doas.user': username}}
Finally, in models/core.py you have to add the following bit in the get_sqla_engine def
params = extra.get("engine_params", {}) # that was already there just for you to find out the line
self.cursor_kwargs = self.db_engine_spec.get_cursor_configuration_for_impersonation(
str(url), self.impersonate_user, effective_username) # this is the line I added
...
params.update(self.get_encrypted_extra()) # already there
#new stuff
configuration = {}
configuration.update(
self.db_engine_spec.get_configuration_for_impersonation(
str(url),
self.impersonate_user,
effective_username))
if configuration:
params.update(configuration)
As you can see I just shamelessy pasted the code from the PR. However this kind of works only for the SQL lab as I already said. For the dashboards there is an entirely different way of querying Impala that I did not still find out.
This means that queries for the dashboards are handled in a different way and there isn't something like this
with closing(engine.raw_connection()) as conn:
# closing the connection closes the cursor as well
cursor = conn.cursor(**database.cursor_kwargs)
My gut (and debugging) feeling is that you need to first understand the sqlalchemy part and extend a new ImpalaEngine class that uses a custom cursor with the impersonation conf. Or something like that, however it is not simple (if we want to call this simple) as the sql_lab part. So, the trick is to find out where the query is executed and create a cursor with the impersonation configuration. Easy, isnt'it ?
I hope that this could shed some light to you and the others that have this issue. Let me know if you did find out another way to solve this issue, or if this comment was useful.
Update: something really useful
A colleague of mine succesfully implemented impersonation with impala without touching any superset related, but instead working directly with the impyla lib. A PR was open with the code to change. You can apply the patch directly in the impyla src used by superset. You have to edit both dbapi.py and hiveserver2.py.
As a reminder: we are still testing this and we do not know if it works with different accounts using the same superset instance.

getting a "need project id error" in Keen

I get the following error:
Keen.delete(:iron_worker_analytics, filters: [{:property_name => 'start_time', :operator => 'eq', :property_value => '0001-01-01T00:00:00Z'}])
Keen::ConfigurationError: Keen IO Exception: Project ID must be set
However, when I set the value, I get the following:
warning: already initialized constant KEEN_PROJECT_ID
iron.io/env.rb:36: warning: previous definition of KEEN_PROJECT_ID was here
Keen works fine when I run the app and load the values from a env.rb file but from the console I cannot get past this.
I am using the ruby gem.
I figured it out. The documentation is confusing. Per the documentation:
https://github.com/keenlabs/keen-gem
The recommended way to set keys is via the environment. The keys you
can set are KEEN_PROJECT_ID, KEEN_WRITE_KEY, KEEN_READ_KEY and
KEEN_MASTER_KEY. You only need to specify the keys that correspond to
the API calls you'll be performing. If you're using foreman, add this
to your .env file:
KEEN_PROJECT_ID=aaaaaaaaaaaaaaa
KEEN_MASTER_KEY=xxxxxxxxxxxxxxx
KEEN_WRITE_KEY=yyyyyyyyyyyyyyy KEEN_READ_KEY=zzzzzzzzzzzzzzz If not,
make a script to export the variables into your shell or put it before
the command you use to start your server.
But I had to set it explicitly as Keen.project_id after doing a Keen.methods.
It's sort of confusing since from the docs, I assumed I just need to set the variables. Maybe I am misunderstanding the docs but it was confusing at least to me.

undefined method 'path' for nil:NilClass using chargify_api_ares gem

I feel like this should be a simple problem, but I'm pulling my hair out trying to track it down. I'm installed the chargify_api_ares gem, but can't do even basic things such as
Chargify::Subscription.create
As I get this path error. I feel like this must be a gem issue somehow but don't know where to go from here.
UPDATE: bundle show chargify_api_ares shows the correct path, I just somehow can't access it. Still trying random environment related things.
Looks like this is the source of the problem, in active_resource\base.rb:
# Gets the \prefix for a resource's nested URL (e.g., <tt>prefix/collectionname/1.json</tt>)
# This method is regenerated at runtime based on what the \prefix is set to.
def prefix(options={})
default = site.path
default << '/' unless default[-1..-1] == '/'
# generate the actual method based on the current site path
self.prefix = default
prefix(options)
end
As I understand it, Chargify.subdomain should be setting the site.path, but I don't understand activeresource well enough yet to know what's happening and will continue to dig.
I too had the same issue.
I executed the following on the console
Chargify.configure do |c|
c.api_key = "<<api_key>>"
c.subdomain = "<<subdomain>>"
end
After that performing any Chargify console commands went through fine.

Rails 3, why model update fails silently ? how to debug DB?

I have added new fields for my devise user, but, now, I can't update the student record, although I get the message:
You updated your account successfully.
But, the DB is never updated!
The new fields have attr_accessible and attr_accessor
Is it because there is a foreign keys in the new fields ? I have added country id to associate the user with his country, is this a reason for not updating ?
How can I debug the DB error occurred ? I tried to use update_attributes! in the devise function: update_with_password, but, no luck, no errors, just: You updated your account successfully.
I've noticed that there is no SQLite UPDATE command issued at Server Development log, why ?
Any help please ?
I found the solution, I should not use attr_accessor as its for those attributes that are not stored directly into DB.
I hope this will help some one.
Try raising a exception or logging by adding an after_filter to your update action on the UserController. Try overriding the controller action (and call super) if you dont have a hook to that code.

How can I see the SQL ActiveRecord generates?

I'd like to check a few queries generated by ActiveRecord, but I don't need to actually run them. Is there a way to get at the query before it returns its result?
Both of these articles should help you do what you want.
http://weblog.jamisbuck.org/2007/1/8/watching-activerecord-do-it-s-thing
http://weblog.jamisbuck.org/2007/1/31/more-on-watching-activerecord
i think it's buried in:
construct_finder_sql,
http://groups.google.com/group/rubyonrails-talk/browse_frm/thread/38c492e3939dd9bf/?pli=1
tail -f log/development.log
Works in default settings or when you set your logger level to DEBUG.
Jamis' article is outdated, or at least doesn't work my Rails app (possibly due to some other reason with a 3 year old 30,000 line app). However this works in a console any time:
ActiveRecord::Base.connection.instance_variable_set :#logger, Logger.new(STDOUT)
