Is it possible to access all the fields from a previous step as a collection like json rather than having to explicitly setting each one in the input data?
Hope the screenshot illustrates the idea:

The idea is I have a step that lookup responses in a google form and I wish to parse the result to display all the Questions and Answer into an email.
Hope this is possible
Thanks
David here, from the Zapier Platform team. Unfortunately, what I believe you're describing right now isn't possible. Usually this works fine since users only map a few values. The worst case is when you want every value, which it sounds like you're facing. It would be cool to map all of them. I can pass that along to the team! In the meantime, you'll have to click everything you're going use in the code step.
If you really don't want to create a bunch of variables, but you could map them all into a single input and separate them with a separator like |, which (as long as it doesn't show up in the data), it's easy to split in the code step.
Hope that helps!
The simplest solution would be to create an additional field in the output object that is a JSON string of the output. In a Python code step, it would look like
import json
output = {'id': 123, 'hello': 'world'}
output['allfields'] = json.dumps(output)
or for returning a list
import json
output = [{'id': 123, 'hello': 'world'},{'id': 456, 'bye': 'world'}]
for x in output:
x['allfields'] = json.dumps(output[output.index(x)])
Now you have the individual value to use in steps as well as ALL the values to use in a code step (simply convert them from JSON). The same strategy holds for Javascript as well (I simply work in Python).
Zapier Result
Fields are accessible in an object called input_data by default. So a very simplistic way of grabbing a value (in Python) would be like:
my_variable = input_data['actual_field_name_from_previous_step']
This differs from explicitly naming the the field with Input Data (optional). Which as you know, is accessed like so:
my_variable = input['your_label_for_field_from_previous_step']
Here's the process description in Zapier docs.
Hope this helps.
I've got a JSON hash of hashes returned by a website API that I want to parse and display based on a specific key's value within the internal hashes.
I can think of solutions that would achieve this, but they would take a number of lines of code and don't seem efficient. Surely there must be a way to natively in Rails, given the focus on convention over configuration. I've googled around a bit, but found nothing that covers this issue.
Sample Response from API:

Potential solution would be to go through each internal hash, determining value of relevant key value, then store, based on where the key value places it compared to already tested hashes. When complete, return.
Ok so if you have objects that are set up to parse this information, those objects can build themselves based off the parameters of your hash. So you could do something like this
object = MyObject.create(your_hash_parameters)
Where your_hash_parameters are the parameters that you presented in your example.
I'm not sure what would happen if there were more paramaters than your object knew what to do with, if it would still build itself or not. If that is the case, you could use the delete_if method to exclude attributes that are unwanted.
One more note, if this isn't something that you want saved to your database, and its only to display temporary information. I would set up a model with attr_accessors that represent the attributes that you are displaying.
As told in comment, I'd create an ActiveResource object and add relevant methods to it.
I'm doing an application using mongodb and mongoid and I'm facing a problem where I need to map something in one document to something in another document. My plan is to store something in a document that I can then use to figure out what value for it to fetch from a different collection. But, this is more generally a ruby question about how I can fetch data from deep within a hash.
I have a structure something like this:
Widget
Sections
0
Fields
0
value: foobar
If that makes sense. Let's say I want to get the value of the first field in the first section, I would do something like:
#widget.sections[0].fields[0].value
No problem.
Now the question is, how can I do this with all of that as a string? What I want to do is store within the database a mapping value. So I've have a key/value with something like:
mapping: "sections[0].fields[0].value"
Now how can I use that to get the data from #widget? I've tried #widget.send "sections[0].fields[0].value" but that does not work... I can do #widget.send "sections" and get back an array of sections, but I'm not quite sure how to take it further...
So to summarize, I can do this:
#widget.sections[0].fields[0].value
if I have #widget and a string "sections[0].fields[0].value" how can I execute that?
#widget.instance_eval("sections[0].fields[0].value")
should do the trick.
I have a difficult situation.
I let the the user create a form through a Rich Text Editor and then I save this.
So for example, I save this literally into my DB:
http://pastebin.com/DNdeetJp (how can you post HTML here? It gets interpreted, so now I use pastebin...)
On another page I wrap this in a form_tag and it gets presented as it should be.
What I want to do is save this as a template and save the answers as a hashmap to my DB.
This works well, but the problem is I want to recreate what checkbox/radiobutton/... is selected when the user goes back to the page. So I want to fill the form with the answers from the hashmap.
Is there a way to use a 'dummy' model or something else to accomplish this?
Thanks!
Since you're pasting in raw HTML which is not properly configured as a template, it is more difficult to enable the proper options based on whatever might be stored in your DB.
The reliable approach to making this work is to use Hpricot or Nokogiri to manipulate the bit of HTML you have and substitute values accordingly. This isn't too hard so long as you can define the elements in that form using a proper selector. For example, create a div with a unique id and operate on all input elements within it, comparing the name attribute with your properties. There may even be a library for this somewhere.
The second approach is to use JavaScript to enable the options in much the same fashion. This seems like a bit of a hack since the form itself will not have a proper default state.
I am working on some code that scrapes a page for two css classes on a page. I am simply using the Hpricot search method for this as so:
webpage.search("body").search("div.first_class | div.second_class")
...for each item found i create an object and put it into an array, this works great except for one thing.
The search will go through the entire html page and add an object into an array every time it comes across '.first_class' and then it will go through the document again looking for '.second_class', resulting in the final array containing all of the searched items in the incorrect order in the array, i.e all of the '.first_class' objects, followed by all the '.second_class' objects.
Is there a way i can get this to search the document in one go and add an object into the array each time it comes across one of the specified classes, giving me an array of items that is in the order they are come across in on the page i am scraping?
Any help much appreciated. Thanks
See the section here on "Checking for a Few Attributes":
http://wiki.github.com/why/hpricot/hpricot-challenge
You should be able to stack the elements in the same way as you do attributes. This feature is apparently possible in Hpricot versions after 2006 Mar 17... An example with elements is:
doc.search("[#href][#type]")
Ok so it turned out i was mistaken and this didn't do anything different to what i previously had at all. However, i have come up with a solution, wether it is the most suitable or not i am not sure. It seems like a fairly straight forward for an annoying problem though.
I now perform the search for the two classes above as i mentioned above:
webpage.search("body").search("[#class~='first_class']|[#class~='second_class']")
However this still returned an array firstly containing all the divs with a class of 'first_class' followed by all divs with a class of 'second_class'. So to fix this and get an array of all the items as they appear in order on the page, i simply chain the 'add_class' method with my own custom class e.g. 'foo_bar'. This then allows me to perform another search on the page for all divs with just this one tag, thus returning an array of all the items i am after, in the order they appear on the page.
webpage.search("body").search("[#class~='first_class']|[#class~='second_class']").add_class("foo_bar")
webpage.search("body").search("[#class~='foo_bar']")
Thanks for the tip. I hadn't spotted that in the documentation and also found another page i hadnt seen either. I have fixed this with the following line:
webpage.search("body").search("[#class~='first_class']|[#class~='second_class']")
This now adds an object into the array each time it comes across one of the above classes in the document. Brilliant!
