Here are some simple steps that can help you troubleshoot multi-parameter attribute assignment errors in Rails 1.
Don’t let Windows errors hold you back.
Try what would
#date_select emulate? If yes, identify the second part of the answer.
If you want to assign a DateTime to a database, it must be a DateTime object. Here you are faced with an array
["2013-09-16", strings, "15:30"].
Now you can easily evaluate these strings using date and time regular expressions:
d+)-(? d+)-(? d+)/ =~ params[ 'start(1s)' ]/(? d+):(? d+)/ =~ Parameter[ 'start(2s)' ]datetime = DateTime.new (year.before_i, month.before_i, day.before_i, hours.before_i, minutes.before_i )
This saves the moment, month, day, hour, and minute in local variables, and based on that creates an initial data hour that can then be assigned to the model.
However, databases cannot store Ruby DateTime instances as they are, so Tracks performs a conversion when storing a date or datetime field to convert it to a range. The
#to_s(:db) method is used which gives:
DateTime.now.to_s(:db) # "2013-09-17 => 09:41:04"Time.now.to_date.to_s(:db) Number => "2013-09-17"
So you could just concatenate your strings, whichwould use the correct date representation, but that wouldn’t be a good idea, mostly:
- This is an implementation detail, nothing to suggest that the format of this big day will not change in the next version of the song.
- If you try to exercise with a date and time after assignment and before save (as with before_save), the software will be a string, not just a date and time.
Use Active_record Date/time Helper
Because this would always be tedious, Train Track provides helpers for creating and using date and time form entries.
FormBuilder#datetime_select takes the desired attributes one by one, and the hobby takes all the input:
<%= f.datetime_select: %>
Actually, 5 prompts will be created, each “start(1i)” (year), “start(2i)” (month), “start(3i)” (day), “start(4i)” (hours ). and/or (minutes) “start(5i)”.
If this sounds familiar, the simple fact is that this is exactly the data we extracted to create the date/time in the first part of this answer. When the client hashes the niche date and time with eWith these exact keys, the device creates a date and time object using their values, as we did in the first part.
The problem with your purchase code is that you just provided “start(1i)” and “start(2i)”. Rails not really, because you only ran it once every 12 months and every month, much more than it takes to determine the date/time.
Ruby Date expects parameters; Date The contour parameters corresponding to this field were then serialized to the operator as Birth 1i , Birth 2i , Birth 3i.
Assigning this hash to the data and time field using these exact keys will add a date and time object based on their estimates, just like we did in the first part. The goal here is to collide and crash with a virtual attribute of my design and style. When creating a document, the time is not as high as high. In this case, all “i” are related to DateTime. I don’t know how to continue because unfortunately the other posts weren’t informative. This will store the year, day, day, hour and minute in your own local variables and create a new fixed time data for them.x, which you can then assign to your model.
I don’t know how well this should work in the market. In the meantime, how do we get the job done? One problem I had with this formula was that the time was in UTC and not in our local time zone. MembershipsController just throws errors when assigning multi-parameter completions After some searching for a solution on the wide web, as any self-respecting programmer does, and found that many others are facing the same problem.
This works great if you’re using a database-select-and-store partner, Rails takes care of expanding the multi-parameter attributes and posting to the collection domain. This corresponds to a column in my database defined with ActiveRecord person date type.
However, databases cannot store Ruby DateTime instances in the supermarket, because behind the scenes, when a specific date or date/time field is stored to be converted to a string, rails actually does the conversion. How I Decided on the Options: I PreferI guess this fix will be done by adding it to the template file, right? What is the correct way to handle this attribute classification without showing the random array iteration associated with such parameters?
