Allow casting new votes with Rules

Wow !!! will be using it and post back the results shortly ...

Hello can u tell me how do i apply this patch on a live site ?

Suppose this functionality should have reverse action to remove vote

@Itangalo I can verify that this patch works for me and I am able to use Rules to cast new votes.

@Energyblazar Applying patches

This patch needs re-roll (remove trailing white-spaces) and some work to include actions to remove vote

I don't think the patch needs to be held up for the additional functionality of removing votes. Not a bad addition, but I think the likely use case is to prepopulate votes, it is for me.

I just used this patch to prepopulate a five star field with votes before allowing anon voting. Works great.

how did u do it timb ?

@Energyblazar: I found the easiest way to create a new vote on a node: is to load a node that has already been voted on and then use it's vote values to populate the values on a new vote, except for maybe changing out the score. confusing? ... maybe a pic would help

heya timb thanks...

but still i am not able to figure out what ya have done even after watching screenshot of yours...

I tried to go to Rules > Add a New Rule , no where in any of the chosen option could i find these "Entity to vote on", "Voting User","Voting Value", "Vote Tag" stuff.

Can you please explain a little more in detail.

P.S: I am fairly new to this drupal and rules thingy...

Thank you...

yo e.b.: it sounds like you may not have the module patched properly. Try the instructions in comment #7 to manually use the patch command. In my install it appears as: Add new rule => Cast a vote

Heya Timb...

Been two days and still i am clueless why i cant get the option "Cast A Vote" When i click on Add New Rules.

Please help me enlighten myself...I did add the patch manually.... here it is...thanks again

Can anyone atleast give me a hint as to where i am going wrong or missing a thing or two ?

Its nothing complex...

If you see comment #12 timb has posted a screenshot, which he says, he achieved this rules functionality with use of your patch..

Now i did patch it manually using instructions on comment # 7.

But i am still unable to find Add new rule => "Cast a vote" functionality in rules...

Now can u look at the code and tell me wether i have applied the patch right ?

If i have applied it right then where excatly should i be looking for "Cast a Vote" functionality in rules ?

yes yes yes thank u Itangalo in actions there is cast a new vote.... silly me...i looked every where not in the list of actions...THANKS AGAIN !!!

Thanks for this patch. I'm trying to set up rules to cast a vote on one of two widgets depending on what the user selects for a boolean field in a node's comment form. After applying the patch I can see "Cast A Vote" as an option under the list of Actions. However, I'm not sure how to specify which of the two Rate widgets to vote on. I'm also getting an error when trying to input +1 as a voting value.

My current rule configuration:
Event: After Saving a New Comment
Conditions:
Content is of type X
Data comparison (checks if user chose the targeted boolean value)

Any ideas on how to show the two rating widgets in the data selector?

Thanks in advance.

hmm... thats kinda complex part i guess u may need do some custom coding in rules for it.... here is some hint.. http://nodeone.se/sv/node/829

@Energyblazer
I'm not very good with code at the moment but I'll keep this for future reference. Thanks

@Energyblazer
I was able to copy a previously made vote from a set node then modify it before attaching it to a new node to guarantee certain values. See my comment #12
maybe this work in your case to load 2 different votes based on your boolean

Can anyone who has used this with the Rate Module please provide a short description of the formatting used for the "Voting Value" field for each rate widget type.

In my case, I have a rate widget with values of type "option". In the rate widget page the values for my two options are numbered "1" and "2". When i go to the rules "cast a vote" configuration page I'm not sure what to input in the "vote value" field. I tried "1" and "+1" but neither seem to work. This could be the correct format and it's possible that it's not working because I made a mistake some where else.

Any ideas?

Thanks Timb looked at ur comment #12 and was trying to figure out how to get passed-node in Entity to vote on, vote-template:0:user in voting value, Voting value as passed-score and voting tag as vote-template:0:tag ..... but am still clueless how to achieve as you have done in your screenshot ... can u guide me better..

I think this issue should be top of the issue queue.

The silly thing about this issue, If user case a vote, and X condition is met, then set to previous vote and/or remove vote, then another vote has to be casted.

(Until there is a pre cast event)

Thanks for this patch.
I got it working in rules by using a field to pass the default value (of 40) and then adding an offset (of 40)
In my case the ratings seem to be out of 100.
The value of 80 is passed to 'vote' which results in a 4/5 Fivestar rating on the node.
The Fivestar widget needed to be set to 'rating while viewing' on the content type.

+ // @TODO: Add the 'value_type' parameter, now defaulting to percent.

This also need to be fixed before committing.
It's not so useful without it.

It's been a while since anyone else has worked on this so assigning to me and I'll make a few additions.

Hello somebody can help me ? I installed the patch easy but when i configure my rule with a "after save a node" the vote that i configured is not made it.

My rule try to create a vote in a node referenced "node:field-usuario" (Entity reference field) when i created a specific node.

This are my screenshots

Whoops, this one totally slipped off my radar (if anyone else has this problem, show your support at #1621714: Allow to bookmark/favorite issues without abusing the Assigned field or issue tags :)).

I actually did make the changes I was talking about in #30, I just have to make a patch out of it.

Hi

When I use rules I can create an action when a vote happens, but I cant create a vote as an action at all.

Has this been applied?
