Utilisation d'un fichier .py comme template dans Django
Sebastien
Bonjour ,
Je souhaite utiliser un fichier .py en tant que template et pas un fichier HTML .
Avez vous une solution ?
Ci dessous voici mon template python . C'est un fichier que j'aie nommé app.py
Ci je lance la commande python app.py . Le gabarit fonctionne et s'affiche bien dans mon navigateur Chrome .
Mais je n'arrive pas à le lancer à partir de Django avec la commande python python manage.py runserver
import dash
import dash_bootstrap_components as dbc
from dash import dcc
from dash import html
import pandas as pd
import plotly.express as px
import requests ,base64
from io import BytesIO
import plotly.graph_objects as go
import plotly.express as px
from collections import Counter
from dash.dependencies import Input, Output
df = px.data.iris() # iris is a pandas DataFrame
fig = px.scatter(df, x="sepal_width", y="sepal_length")
# ci dessous je fais un lien vers le thème de bootstrap que j'ai choisit nommé DARKLY
app = dash.Dash(external_stylesheets=[dbc.themes.DARKLY])
# ci dessous je fais une mise en page de mon application finale avec une div vide
#app.layout = html.Div([])
# ci dessous je fais une mise en page de mon application finale avec un composant de bootstrap nommé container
# sachant que container est un composant de base à connaitre autant que row et col
# il fait parti des fondamentaux de bootstrap
app.layout = dbc.Container([
# 1 ère ligne avec 1 colonne
dbc.Row([
dbc.Col([
html.H1('Mon header')
])
]),
# 2 ème ligne avec 3 colonnes
dbc.Row([
dbc.Col([
html.H2('Nombre de cas confirmés')
],width=3),
dbc.Col([
html.H2('Nombre de décès'),
dcc.Graph(figure=fig)
],width=6),
dbc.Col([
html.H2('Nombre de personnes hospitalisées')
],width=3),
]),
# 3 ème ligne avec 1 colonnes symbolisant mon footer
dbc.Row([
dbc.Col([
html.H3('Mon footer')
])
])
])
if __name__== '__main__':
app.run_server(debug=True ,port=8888)

On dirat que :
'django_plotly_dash'
n'est pas dans ton
settings.py. Tu l'as bien mis ?
Tu as des imports dépréciés. Tu dois bien importer de cette manière :
from dash import dcc, html
Et si tu fais bien ton runserver après ça devrait aller je pense.
C'est bon pour toi ?

Tu peux mettre ton code au format code ?
ça sera plus simple ^^
Car là j'ai des underscore qui doivent disparaitre entre deux
Merci d'avance
C'est ce que je fait et j'aie constaté que ce bouton faisait des affichages parfois étranges .
Peut - être avec le bouton "quotes" comme ceci ...

Je t'ai fait le formatage.
Tu n'as pas oublié l'url du coup ?
urlpatterns = [
...
path('django_plotly_dash/', include('django_plotly_dash.urls')),
]
Sebastien
Bonjour ,
effectivement , il me manquait
urlpatterns = [
...
path('django_plotly_dash/', include('django_plotly_dash.urls')),
]
et il me manquait aussi
# X-Frame-Options indiquer par la doc officielle
X_FRAME_OPTIONS = 'SAMEORIGIN'
Dans mon fichier settings.py .
Mea culpa , je ne sais pas bien lire les documentations .L'idéal serait que les documentations soient transformées en supports vidéos concrets .
En tout cas coté django-dash-plotly, c'est bon ...
Maintenant , je peux commencer à coder l'application dash avec mon fichier dash_app.py et ne plus me soucier de codage en HTML coté template .
Pour l'instant , j'aie mon dropdown qui s'est chargé mais pas le graphique en barres .
Je vais cherché de mon coté , investiguer la documentation dash et plotly et je cloture ce post .
Merci monsieur !...
