# Problem with the bibliography (biblatex) on TeX STudio

I'm discovering biblatex and i have a few problem or misunderstanding.
I'm actually working with TeX Studio and when i'm trying to run the bibliography, I have the following message:

This is BibTeX, Version 0.99d (TeX Live 2015/W32TeX)
The top-level auxiliary file: rapport.aux
I found no \citation commands---while reading file rapport.aux
I found no \bibdata command---while reading file rapport.aux
I found no \bibstyle command---while reading file rapport.aux
(There were 3 error messages)

The thing is I trying a lot of different solutions shown in different topics and no one had the correct solution to my problem...

Here is my code:

  \documentclass[a4paper, 12pt]{report}

\usepackage{geometry}
\usepackage[francais]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{enumerate}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{mathrsfs}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\usepackage[section]{placeins}
\usepackage{verbatim}
\usepackage{array}
\usepackage{multirow}
\usepackage{multicol}
\usepackage[final]{pdfpages}
\usepackage{siunitx}
\usepackage[style=authoryear]{biblatex}
\usepackage{csquotes}
\usepackage[final]{pdfpages}
\usepackage{float}
\usepackage{circuitikz}
\usepackage{geometry}
\usepackage{titlesec}
\usepackage{xcolor}
\usepackage{sectsty}
\usepackage{biblatex}
\usepackage{filecontents}

\begin{filecontents*}{rapport.bib}
@online{cim-wiki,
author = {Wikipedia},
title = {Common Information Model (electricity)},
date = {11.04.2016},
url =    {https://en.wikipedia.org/wiki/Common_Information_Model_(electricity)},
}
\end{filecontents*}

\bibliography{rapport}
\chapter{Bibliographie}

\printbibliography
\end{document}


new version of the code:

   \documentclass[a4paper, 12pt]{report}

\usepackage{geometry}
\usepackage[francais]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{enumerate}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{mathrsfs}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\usepackage[section]{placeins}
\usepackage{verbatim}
\usepackage{array}
\usepackage{multirow}
\usepackage{multicol}
\usepackage[final]{pdfpages}
\usepackage{siunitx}
\usepackage{csquotes}
\usepackage[final]{pdfpages}
\usepackage{float}
\usepackage{circuitikz}
\usepackage{geometry}
\usepackage{titlesec}
\usepackage{xcolor}
\usepackage{sectsty}
\usepackage[style=authoryear,backend=biber]{biblatex}
\usepackage{filecontents}

\bibliography{rapport}
\begin{document}
\chapter{Bibliographie}
\nocite{cim-wiki}
\printbibliography

\end{document}


with the following bib file:

 @online{cim-wiki,
ALTauthor = {Wikipedia},
ALTeditor = {editor},
title = {Common Information Model (electricity)},
date = {4 February 2016, at 04:26.},
url = {https://en.wikipedia.org/wiki/Common_Information_Model_(electricity)},
OPTurldate = {11/04/2016},
}


Here is a more minimal AND working example, using biber not bibtex

Note that biber complains about the format of the date, so you'll need to look that up in the biblatex manual.

You probably mean urldate not date, and then the syntax is YYYY-MM-DD, so

urldate = {2016-04-11},


in this case.

 \documentclass[a4paper, 12pt]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[style=authoryear]{biblatex}
\usepackage{csquotes}
\usepackage{filecontents}

\begin{filecontents*}{rapport.bib}
@online{cim-wiki,
author = {Wikipedia},
title = {Common Information Model (electricity)},
urldate = {2016-04-11},
url =    {https://en.wikipedia.org/wiki/Common_Information_Model_(electricity)},
}
\end{filecontents*}

\bibliography{rapport}

\begin{document}

\chapter{Bibliographie}

\cite{cim-wiki}

\printbibliography
\end{document}
