WebKit Report : system revolution for OpenERP

26 juin 2010

Dear community and partners,

At the last Community & Partners meeting, Camptocamp participated to several workshops on various topics. One of them was on the reporting system of OpenERP; following this workshop, some conclusions have been drawn on which direction to follow. Mainly, we though that we needed a more powerful engine than RML (for better performance) as well as something more easy to use (to reduce costs).

Today, we do have such a solution, including all the requirements discussed together back in March !!

Camptocamp Business Solutions’ team is proud to announce the release of OpenERP WebKit Report as a module for the V5.0 of OpenERP. You can find it in the extra-addons branch as the module called "c2c_webkit_report". This newly released module includes the following main features:

  • OpenERP Compliant (translation, formatLang, pdf/html output)
  • HTML & CSS-3 Reports definition
  • Multi-plateform (Windows, Linux, OS X)
  • Multi-header support with full image support (per report and/or per company)
  • Multi-company compliant
  • Full JavaScript support
  • Easy paper-size, margin and format selection
  • And more : Raw HTML debugger, futur full integrated WYSIWYG editor, …

Watch the live demo here:

I want to thank all the participants for their contributions and the constructive work that has been done for drafting the specifications, particularly Nicolas Bessi who created this amazing module!

We are going to work hand-in-hand with OpenERP SA to integrate this new report engine into the core of the future version 6.0 of OpenERP. We hope, you will enjoy it!

Best regards,

Joël Grand-Guillaume

    I’ve intalled c2c_webkit_report on my ubuntu server 10.04, wkhtmltopdf I’ve installed too, but I’ve still get error :
    IOError: [Errno 2] No such file or directory: u’/tmp/WebKitinvoice1284721660.73.pdf’
    on, explained that wkhtmltopdf need xserver, It mean I must install xserver on my ubuntu-server to make webkit_report running well on my server, isn it

  2. Nicolas dit :

    The module is name report_webkit on the addons branch of V6.


  3. Mark dit :

    amazing work, I searched launchpad but didn’t find an addon for V6 RC.

    I know it’s only a RC but I would try the addon if you could tell me where I should download it.



    • Joël Grand-Guillaume dit :


      Thank you for your interest ! All our work is now fully integrated in the core, after a hard work hand-in-hand with OpenERP SA.

      The name is « report_webkit », and you can use it as if it was always here !



  4. Dennis van Velzen dit :

    The HTML tag got filtered:

    {div id= »factuur_header_logo »}${helper.embeed_logo_by_name(‘logo’)}{/div}

    The from DIV tags are replaced by { and }.

    Another question:

    Is there a community forum available?

  5. Dennis van Velzen dit :

    Dear CampToCamp (c2c),

    I installed all the required libs and used the htmltopdf binary from google code and it is working stunning 🙂 on my dedicated Ubuntu server.
    And already use it in production.

    Where can I find documentation of your reporting module?

    The question is as follows:

    I place logos and images with the following html tag:


    In the style sheet I specified the image width and height:

    #factuur_header_logo img {

    But I want to add a page background using the style sheet.

    background-repeat: no-repeat;
    background-position: bottom;
    background-image: url(???)

    I can upload a image to the server, and specify this in the URL but maybe there is a better solution, for example a helper object?

    Kind Regards,
    Dennis van Velzen

      Apparently you miss some libs. You need to install the webkit htmltopdf engine.

      As it says, download it from



  8. Nicolas dit :


    @Discovery, il semble que le module Python ‘commands’ ne soit pas disponible dans la distribution de Python utilisée. Cela est probablement du au fait que ‘command’ n’est jamais utilisée dans les addons de base et n’a pas été inclue dans l’installeur Python OpenERP. Normalement ‘commands’ fait partie des librairies standards de python 2.x


  9. Nicolas dit :


    Ray, can you please fill an bug on launchpad in extra-addons and put the complete error trace.
    I have too few info to help you here.



  10. Ray dit :

    helo joel,

    I tried using wizard in c2c_webkit_report but it give error that NO SUCH FILE OR DIRECTORIES .While debugging I came to know that I am getting error in file and in genreate_pdf method.

    So can u assist to solve this above error.


  11. Ray dit :

    First of all very nicely done.

    I am using your module and it is working fine.

    I like to know, can you assist me to use wizard for customised the required field before generating the pdf report.

    Since I want a few field to be selected before generating the report


    • Joël Grand-Guillaume dit :


      Thank you for your interest, we appreciate the success of our new reporting tools 🙂 Unfortunately, I will not answer your question directly. The documentation provided by OpenERP SA explain how you can extend / create new wizard on reports.

      Our reporting system works exactly the same than the standard one and you can extend it as you did with RML.

      Good luck ,



  12. Rémi dit :


    j’essai de télécharger ce module sur un serveur windows. Le serveur est protéger par Kaspersky (à jour). Et lors du téléchargment, Kaspersky bloque le fichier « wkhtmltopdf.exe » qui est soit disant infecté par un programme malveillant du nom de « hoax.win32.ArchSMS.ahd ».

    J’ai essayé d’effectuer le téléchargement depuis :

    et j’ai toujours le même résultat :
    18/08/2010 10:43:22 Infecté programme malveillant Hoax.Win32.ArchSMS.ahd

    S’il vous plaît est-ce que quelqu’un sait si cette menace est vraiment dangereuse ? Est-ce vraiment une menace ? Et si oui, comment l’enlever ? Parce que je n’obtiendrai pas l’autorisation de l’utiliser tant que cette menace sera détectée, ce qui est vraiment dommage !


    • Joël Grand-Guillaume dit :


      Nous avons fait le nécessaire et il semble selon nos tests que ce fichier .exe ne représente aucune menace. Il est considéré comme un virus pour une raison inconnue (cela peut se produire en de rare occasion). Cependant, et dans un soucis continu d’amélioration, nous avons retiré cet executable du module.

      Nous vous enjoignons donc à reprendre la dernière version du module et à installer la librairie de manière séparée.

    Oups, I ended up finding it here:

    My bad, should have looked better first. Hope it can help somebody else! 😉

  14. 5H dit :

    I guess I’m just not familiar enough with Bazaar, Launchpad and such but I can’t seem to find « c2c_webkit_report » in lp:openobject-addons.

    Any guidance would be very much appreciated. Thanks in advance!

  16. wabi dit :


    i have successfully installed the c2c_webkit_report as you described it in your sample video and its working nicely in reporting in english.

    I haven’t found out how to configure the webkit_reports to display translated reports (german, french ) as well.

    If the partner language is set to a different language than english, it seems that the reports do translate « formatLang » entries correctly but leave other words to be translated unparsed.

    For example, on an invoice, currencies and the partners country name are translated/converted correctly into german but « Invoice » « VAT: », « Total: » etc. are not translated at all.

    Am i missing an important installation/configuration step ?

    Is there some additional documentation/video available on how to do multilanguage capable webkit_reports ?

    Best regards


    • Joël Grand-Guillaume dit :


      We are still working hands-in-hands with OpenERP to fix this issue. We want to include the report parsing in the translation like it is with other standard report.

      We could have done a temporary solution, but we prefer to wait till having the right one. We’ll keep you inform on Planet Openobject about that !

      Thanks for using c2c_web_kit_report.



  17. Jim Norman dit :

    Very nicely done. Can you estimate when this will be available in Trunk?


    • Joël Grand-Guillaume dit :


      I went to belgium a few weeks ago and I had a talk with OpenERP’s team about the trunk integration. They are responsible for doing that part, so I can’t give you an precise date, but it’ll be done when the 6.0 will be released.



  18. interfasys dit :

    OK, bug filed.
    Regarding the header, I created a new IMG entry and a new header, I assigned them to my company, went to invoices and pressed on the webkit invoice button. The c2c logo and header was used instead of my own.

  19. Nicolas dit :


    The module is a standard OpenERP extra-addons you can summit bug in this project.
    I will do a other screen cast that will explain header customization more in details today.



  20. interfasys dit :

    From Launchpad:
    « OpenERP WebKit Report does not use Launchpad for bug tracking. »

    Also, I just tried to create an additional logo and header, but when I generate the invoice, OE still uses the default settings.

  21. Nicolas dit :


    To avoid these unicode problem simply use the entity filter in mako template ${my unicode sting |entity }

    and it will be all set.

    Please post this kind of problem on Launchpad.
