Ah bon tu t'y prend de cette manière, donc tu range par ordre décroissant sur les dates puis prend la première, est dont cela l'ami.
j'ai cette erreur:
Code:

1 2 3 An exception has been thrown during the rendering of a template ("[Semantical Error] line 0, col 72 near 'createdAt DE': Error: 'createdAt' is not defined.") in FrontendDefaultBundle::layout.html.twig at line 26. <i>45</i>
Merci

c.createdAt

Code:

1
2
 
->setMaxResult(1)
