У меня есть поисковая система, которая возвращает массив статей, содержащий статьи.
Однако я хотел бы дать вам немного больше дизайна ленты новостей в Твиттере. Я также хотел бы иметь возможность щелкнуть по нему и развернуть их.
Вот обратный вызов поисковой системы:
from dash.dependencies import Input, Output, State
import dash_core_components as dcc
import pickle
from ..server import app
@app.callback(
Output('output-container-button', 'children'),
[Input('button', 'n_clicks')],
[State('input-box', 'value')])
def update_search(n_clicks, value):
f = pickle.load(open("dashboard/data-mm/google-nlu.p", "rb"))
# let's filter f according to value
articles = []
for article in f:
if value in article['headline']:
# We want to print this
articles.append(article)
print(articles[0])
return dcc.Markdown([f"{article['headline']}\n" for article in articles])
А вот мой 'app.py':
app.layout = html.Div(
[
dcc.Tabs(
[
dcc.Tab(
label='Search article',
value= 'search',
children = article_search() # here handle the potential array
# of articles and put it in form?
)
]
)
]
)
На данный момент это выглядит так:
Каждая черная линия article['headline']. Вот article[0]:
{'headline': 'this is the headline',
'body': 'Lorem Ipsum is simply dummy text of the printing and typesetting '
'industry. Lorem Ipsum has been the industry's standard dummy text '
'ever since the 1500s, when an unknown printer took a galley of '
'type and scrambled it to make a type specimen book. It has '
'survived not only five centuries, but also the leap into '
'electronic typesetting, remaining essentially unchanged. It was '
'popularised in the 1960s with the release of Letraset sheets '
'containing Lorem Ipsum passages, and more recently with desktop '
'publishing software like Aldus PageMaker including versions of '
'Lorem Ipsum.',
