我正在尝试检索与密钥var http = require('http');
var fs = require('fs');
http.createServer(function(req, res) {
fs.readFile('input.txt', function(err, data) {
res.writeHead(200, {
'Content-Type': 'text/html'
});
if(err) {
console.log('Error: ', err);
res.end();
} else {
data = data && data.toString().replace(/\*/g, '');
res.write(data);
res.end();
}
});
}).listen(8080);
相关的嵌入文档,但使用jinja将其循环到模板中却没有成功。
目前,review
变量正在检索确切的产品,正如我从终端上的印刷品中看到的那样,但是我无法获得评论并将其循环到模板中。
app.py:
show_reviews
product.html:
@app.route('/review/product_id?=<id>', methods=['POST', 'GET'])
def review(id):
now = datetime.datetime.now()
name=session['name']
post=request.form.get('review')
reviews = mongo.db.products.find_one({"_id": ObjectId(id)})
if request.method == 'POST':
mongo.db.products.find_one_and_update({"_id": ObjectId(id)},{
'$push':{'review':{
'name': name,
'post': post,
'date': now.strftime("%d-%m-%Y")
}
}
}
)
see_review = mongo.db.products
show_reviews = list(see_review.find({"_id": ObjectId(id)}))
print(show_reviews)
return render_template(
'product.html',
reviews=reviews,
name=name, date=now,
post=post,
show_reviews=show_reviews
)
答案 0 :(得分:1)
好的。根据文档的结构,以下是组织代码的方式:
app.py:
@app.route('/review/product_id?=<id>', methods=['POST', 'GET'])
def review(id):
now = datetime.datetime.now()
name=session['name']
post=request.form.get('review')
reviews = mongo.db.products.find_one({"_id": ObjectId(id)})
if request.method == 'POST':
mongo.db.products.find_one_and_update({"_id": ObjectId(id)},{
'$push':{'review':{
'name': name,
'post': post,
'date': now.strftime("%d-%m-%Y")
}}})
see_review = mongo.db.products.find_one({"_id": ObjectId(id)})
show_reviews = see_review['review']
print(show_reviews)
return render_template('product.html', reviews=reviews, name=name,
date=now, post=post, show_reviews=show_reviews)
product.html:
<div class="card-body">
<!--LOOP TO DISPLAY THE COMMENTS HERE-->
{% for rw in show_reviews %}
<p>{{ rw['post'] }}</p>
<small class="text-muted">Posted by {{ rw['name'] }} on {{ rw['date'] }}</small>
<hr>
{% endfor %}
<!-- ENDFOR HERE-->
<hr>
<!--FORM-->
{%if session['email'] != None %}
<form action="{{url_for('review', id=reviews._id)}}" method="POST">
<div class="form-group green-border-focus">
<textarea class="form-control" id="review" name='review' placeholder="Add Review" rows="3" required></textarea>
</div>
<button class="btn btn-success" type="submit">Leave a Review</button>
</form>
{% endif %}
</div>
