Hello,
I have a couple of time field (MySQL data type: time) "start_time" and
"end_time", and I''m trying to use a time_select helper to
save the
data. Here''s how I''m using it:
<%= form.time_select :activity_start_time, :prompt =>
true, :ignore_date => true %>
<%= form.time_select :activity_end_time, :prompt => true, :ignore_date
=> true %>
and I get this error:
2 error(s) on assignment of multiparameter attributes
when it hits the controller at this line:
@activity = Activity.new(params[:activity])
Here''s the parameters:
{"authenticity_token"=>"5MmHPVW9VupApm3Qk17OEaf4M5dTk7iw9HhFbhOM3Q0=",
"activity"=>{"name"=>"",
"notes"=>"",
"activity_start_time(4i)"=>"10",
"activity_end_time(4i)"=>"13",
"activity_start_time(5i)"=>"00",
"activity_end_time(5i)"=>"00",
"activity_date"=>"04/03/2010",
"hours"=>"",
"description"=>"",
"activity_type"=>"40"}}
What am I doing wrong?

Update - I just noticed that it will save a new record without this error if I have the minutes other than "00". But there still is an issue, since it saves the parameters as Year and Month instead of Hour and Minute! So this is interpreted as "activity_start_time(4i)"=>"10", "activity_end_time(4i)"=>"13", "activity_start_time(5i)"=>"05", "activity_end_time(5i)"=>"05", activity_start_time = 2010-05-01 00:00:00 activity_end_time = 2013-05-01 00:00:00 Has anyone encountered this problem? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Well, I found out that I can''t have ANY extra constraints on it. That
seems to make time_select parameters interpreted incorrectly.
Can''t have:
:prompt => true
:include_blank => true
:ignore_date => true
So my form field is reduced to:
<%= form.time_select :activity_start_time %>
<%= form.time_select :activity_end_time %>
and
@activity.activity_start_time = Time.parse("00:00")
@activity.activity_end_time = Time.parse("00:00")
inside the controller, so that the current time won''t be selected by
default for new records. Kind of annoying that I can''t have prompt or
blank at the top. :-\ If anyone has figured out a way to make
time_select work as expected, I''m all ears!

So I just scaffolded, tested and successfully reproduced your problem exactly. Playing around in the console gave some interesting results:>> Activity.new ''activity_start_time(1i)'' => ''2010'', ''activity_start_time(22i)'' => ''11'', ''activity_start_time(100i)'' => ''7'' >> ... activity_start_time: "2010-07-11 00:00:00"So for multiparameter attribute assignment, it just sorts the index number alphabetically and uses the data fields to assign to the object, in order (at least for Time / DateTime objects and likely for Date objects as well). It then appears to begin assigning the data to the fields, starting with the "first" field (year) and moving on, ignoring the actual numeric value of the "index" (such as my 100 above which results in its value becoming the month). So, with the rails helper defaults of ''4i'' and ''5i'', the 5 becomes the ''month'' and ''00'' is an invalid month number. So, this would appear to be a weakness/bug in rails from my perspective. I''d think it should actually strip off the data-type character (the ''i'' chars in this case) and cast the remaining ''index'' characters to a Fixnum (again, at least for date/time types, not sure about aggregates/others) at which point it should respect the number as an offset: 1 => year, 2 => month, and so on so that this usage, as written out by the view helper, actually works as expected. Anyhow, just my two cents. To work around, I''d drop the :ignore_date options in your helpers. Then manually overwrite the YYYY-MM-DD value(s) of these two fields to a consistent default (since I''m assuming you''re not using the date part anyway) so you can compare time values. Then you should file a bug report :-) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for confirming what I was experiencing! (At least I know I''m not seeing things...) I''ve never submitted a bug report for ror - is this the right place? https://rails.lighthouseapp.com/dashboard -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
