Appel liste d'un autre modèle dans une view
Bonjour à tous,
Me formant à l'ASP.NET, je suis le tutoriel de réalisation d'une application MVC + BootStrap.
Je cherche à implémenter une liste des noms de bars dans ma vue pour créer une bière. (histoire d'associer des bières à des bars)
Cependant, je vous avoue que l'aspect de la structure de l'ASP.NET m'est un peu flou pour le moment. Donc comprendre la réalisation d'une telle fonctionnalité m'aiderait beaucoup.
Voici mon code :
BeerController :
Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151

Merci de votre lecture et de votre éventuelle aide.
PS : merci de m'épargner vos liens vers les tutoriels du site que j'ai déjà consulté et étudié, je le rappelle l'aspect me paraît un peu flou sur certains points.
