nested JSON objects about docxtemplater

[shapiromatron]

Looks like I didn't RTFD- sorry

[edi9999]

Haha no problem. Great to see self closing issues

@edi9999 , I think the feature is cool , now I need transfer json to object. haha

[gilesbutler]

Hey,

Sorry but I'm having the same problem and I can't seem to find the answer in the docs, maybe I'm just not reading it right. I'm trying to loop over a nested object using the following:

{#positions}
  {#company}
   {name}
  {/company}
{title}
{/positions}

I also tried:

{#positions}
{company.name}
{title}
{/positions}

But that didn't work either. The strange thing for me is that {title} didn't work for the first few attempts and then it just started working, I'm not too sure why though, I didn't change anything.

Anyway, I'd appreciate any pointers you can give me.

Thanks

Can you please post your json data ?

{#company} {/company} is to loop over arrays, i don't think it works with objects now. You can extend that, it's in scopemanager.loopover I think. I accept PR for this

The company.name syntax works only if you enable the angular parser.

[gilesbutler]

Ah ok, that would be why then as company is an object not an array.

I noticed everything is in CoffeeScript so I probably won't be able to do a PR but I'll take a look anyway.

I've enabled the angular parser but company.name still doesn't work, is that because company is an object or should the angular parser handle both objects an arrays?

[ 
  { 
    company: { 
      industry: 'Internet', 
      name: 'Company 1' 
    },
    title: 'Designer' 
  },
  { 
    company: { 
      industry: 'Internet', 
      name: 'Company 2' 
    },
    title: 'Developer' 
  }
]

Thanks for your help @edi9999

The angular parser works with objects.

You can use the following parser to debug and see which values are undefined:

angularParser = function(tag) {    var e, expr;    try {      expr = expressions.compile(tag);    } catch (_error) {      e = _error;      console.log("parsing didn't work with " + tag);    }    return {      get: function(scope) {        if (scope == null) {          console.log('warning: scope undefined');        }        try {          return expr(scope);        } catch (_error) {          e = _error;          console.log("parsing didn't work with " + tag);          return "undefined";        }      }    };  };

Thanks @edi9999 I can't seem to get the parser working though. Is this the correct setup:

angularParser = function(tag) {
  var e, expr;
  try {
    expr = expressions.compile(tag);
  } catch (_error) {
    e = _error;
    console.log("parsing didn't work with " + tag);
  }
  return {
    get: function(scope) {
      if (scope == null) {
        console.log('warning: scope undefined');
      }
      try {
        return expr(scope);
      } catch (_error) {
        e = _error;
        console.log("parsing didn't work with " + tag);
        return "undefined";
      }
    }
  };
};
var documentPath = "input.docx";

// Create the Docx template file
var doc = new DocxGen({parser:angularParser}).loadFromFile(documentPath);

// Set the templates variables
doc.setTags({
  "firstName" : req.body.firstName,
  "lastName" : req.body.lastName,
  "positions" : req.body.positions
})


// Apply the variables (replace all occurences of {firstName} by req.body.firstName, etc)
doc.applyTags()

// Create a file name from the users first name and last name
var filename = req.body.firstName + '_' + req.body.lastName + '_resume.docx';

var doc = doc.output({
  name: filename
});

I noticed in the docs when you use the angular parser there's an extra data argument being passed in first new DocxGen(data,{parser:angularParser}) but I'm using the load from file wrapper, could this be the problem?

[edi9999]

Yes that's the issue. As you can see in the samples http://javascript-ninja.fr/docxgenjs/examples/demo.html

new DocxGen().loadFromFile("tagExample.docx",options)

Is the way I recommend.

This is a bit weird and will be better designed in version 1.0

[edi9999]

Also you have to require the angular expression package , but i guess you have done that

[gilesbutler]

Excellent, new DocxGen().loadFromFile("tagExample.docx",options) worked!!
Thanks @edi9999 I really appreciate your help with that.

If you need any help testing v1 then I'll be happy to give you hand.

[edi9999]

Great that it helped ! The 1.x branch already exists and you could already test it but is only developped up to 30%.

You can maybe subscribe to the milestone 1.0 0 if you want to get notified of the questions I ask myself

[gilesbutler]

How do you subscribe to a milestone? I can't see anywhere to do that on the milestones page.

[edi9999]

Actually i don't know if it's possible. You can subscribe on all issues tough by watching the repository

[edi9999]

Hey @gilesbutler , version 1.0.0 is out (in beta), you can discuss it over there #92
