Rendering HTML in rails without actually displaying it - ruby-on-rails

My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program.
I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file.
It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them?
Thanks for any help.

Just write the action and view to render the html and text as normal then use the render_to_string method to assign the content to strings
http://apidock.com/rails/ActionController/Base/render_to_string
Then you can run the Model method (hopefully a Class method) to create the zip file using the content you now have in instance variables

Please have a look at the cells plugin.

How to use <?choose:?> inside image url function in BI Publisher template

I'm totally new at BI Publisher and XML templates. I'm trying to update a template to add the logo for a new company/organization. The same templates will be used for 3 separate branches/organizations within JD Edwards.
I'm having trouble trying to conditionally set the url code in the alt text of the dummy image. I think it's because the interpreter can't understand having a <?choose:?> tag inside the url{} definition? How can I use a choose function to return the proper string to the url{} definition?
Two options:
Concatenation:
Just concatenate the source location of your image with an XML variable that holds the brand name.
url:{concat('/folder1/folder2/',BRANCH_NAME_XML_ELEMENT,'_LOGO.JPG')}
Assuming your BRANCH_NAME_XML_ELEMENT is WALMART it will then load the image: /folder1/folder2/WALMART_LOGO.JPG
IF Statements
Make three different dummy images. Each with their respective URL for the logo. Then put each image within an if/end if statement. Will make things look like hell in the RTF file, but it will functionally work when everything is rendered.

Geocortex Workflow Designer Upload File

i was tring to create a workflow with geocortex workflow designer that upload a file in folder.
So to do that, i create a Form that make a file picker and it returns a IList of FileItem.
than i would take the base64 data and write a file, but it show me an error:
Geocortex.Forms.Client.FileItem.Friend Property FileDataBase64 As
String is not accessible in this context beacause it is 'Friend'
the scope of my variable its Flowchart and i can't understand why this error
this error is showned even if i try to access te variable inside the form activity even outside.
thank's every one
It is probably a security related issue.
Make sure that your target directory is writeable by Geocortex workflow. Do a very basic test.
Again do every steps of the process in isolation, in order to pin-point the source of the problem. Poliart.com

Is there a method to display dynamic information to the user BEFORE a build?

Within the Jenkins UI, on the project page, you can use the Description Setter plugin to set a description AFTER a build. Is there any way to dynamically set this before a build? I would want to pull information from a file in the workspace that shows information about files that will be changed when the user builds the project.
Edit: While I haven't found a way to dynamically set the project description, I did find that I can create an Active Choices Reactive Reference Parameter, give it a descriptive name that serves as a title, and then read the contents of a file containing HTML with a Groovy script like so..
// The contents of the file should be HTML
String contents = new File('/tmp/some_file.html').text
return contents
So I made this my last parameter, and it shows the information that I need to show, before the end user clicks the build button. Solves my problem.
I'm going to leave this question open though, in case someone has a better idea.

You will need to select a Choice Type of: Formatted HTML.

Pre-/postprocessing of DSL edited with TMF-based editor

Given:
Some kind of DSL parsed with Xtext parser and then edited by user in TMF-based editor.
When user open file for editing I want first get access to the parse tree of just opened file, modify loaded file content in a some way and then provide to user modified source for editing.
When user wish to save file I again want to preprocess text representation based on actual parse tree and save such altered version.
Is there any Xtext/EMF API to implement such pre-/post- processing?
The goal is to add some content not presented in the physical file, allow user to edit this content and remove it before saving to file. This extra content should be stored separately from DSL source file.
If I understand your question correctly, you want to display additional information in the text editor itself (and not add additional information only to the EMF model, not to the text, for which IDerivedStateComputer could be used).
If the user is not supposed to edit the additional text, the "Code Mining" feature might be useful: https://www.eclipse.org/Xtext/documentation/310_eclipse_support.html#code-mining and https://blogs.itemis.com/en/code-mining-support-in-xtext
To answer the question itself:
Is there any Xtext/EMF API to implement such pre-/post- processing?
No, I am pretty sure there is no such Xtext API for pre-/post-processing files based on their own parse tree (EMF is irrelevant as you want to change the physical content). You could try to mess around with the XtextDocumentProvider (i.e. create your own subclass and register it in the UI module), but this is very likely to break the UI because the line numbers and offsets won't match.
You might have more luck implementing a custom Eclipse action that is executed on the original file and creates a temporary modified copy based on the parsed original file and then opens an editor for the temporary file. Then you could implement a IXtextBuilderParticipant that writes the result back to the original file on save (you have to register it using the org.eclipse.xtext.builder.participant extension point).
Another idea would be not to use an Eclipse action but a tabbed editor using MultiPageEditorPart, with the original as one of three tabs (the composite file and the 'additional info' file being the other two).
The goal is to add some content not presented in the physical file, allow user to edit this content and remove it before saving to file. This extra content should be stored separately from DSL source file.
Couldn't you present this information in another view similar to the 'Properties' view of EMF ? e.g. the user opens file, the Xtext editor opens as well as the 'Properties' view, which presents a way to edit these "extra" information. Upon save of either view, the Xtext save is called and your extra properties are serialized in their own model.

Providing fake data to liquid to render a preview of a template

I have created the ability for users in my system to edit a liquid template that is eventually rendered and turned into a PDF. I would like some ideas as to what the best method would be to create some mock objects to feed the template so as to create a preview for them to see what the final result of their template modifications will be.
The collection of objects passed to the template when it is rendered in real life is fairly complex so I'm thinking at this stage that I can either try and build a temporary model with dependencies in memory, or create some structs that pretend to be the models in question and pass those to the template instead.
Another way could be to instantiate all of this from a yaml file.
Any ideas welcome :)
If you trying to create objects, why dont you use a factory? Are the objects part of the database? You could always use seeds.rb to seed the database with some demo data.
I ended up using a YAML file to build up the structure I needed. It seems that liquid will take a hash of values (and other hashes) instead of the actual models with relationships no problem, so I didn't even need to instantiate the models.
Will happily post an example if anyone is interested.
