Flask 属性错误：'；HTMLString'；对象没有属性'；分页'；

有人帮我写了一些很棒的代码，在这里用一个提交按钮多次显示同一个表单，效果不错，但由于我将有数百个表单需要分页，我过去可以分页页面，但我不知道如何将这些代码与for循环中的表单一起使用。 这是我的代码：（在Greg的帮助下）

我试图使用“表单”是一个列表的事实来对结果进行分页，我显然不知道该怎么做，我已经看过了，但我也不明白！ 非常需要所有的帮助 保罗，向你问好

编辑 我已尝试使用flask_分页，以下是我的代码：

@bp.route('/stock/stock/', methods=['GET', 'POST'])
@login_required
def stock():
    search = False
    q = request.args.get('q')
    if q:
        search = True
    page = request.args.get(get_page_parameter(), type=int, default=1)
    stocks = Stock.query.all()
    forms = []
  #rest of code here#
        pagination = Pagination(page=page, total=stocks.count(), search=search, record_name='forms')
        form.process()  # Do this after validate_on_submit or breaks CSRF token
   return render_template('stock/stock.html',forms=forms, title=Stock, pagination=pagination)

---

这给出了一个不同的错误“TypeError:count（）只接受一个参数（0给定）”我也尝试了“total=forms.count（）”并得到了相同的错误

我讨厌这样做，因为一开始它显示出缺乏耐心，但这个答案可能会帮助其他人，我用两种方法解决了我的问题第一种是决定显示顺序的查询（降序或升序），然后允许我使用flask paginate在几页上显示结果，我意识到我在处理一个列表，其中一个开发者的例子告诉我，这是我的代码

from flask_paginate import Pagination, get_page_args


@bp.route('/stock', methods=['GET', 'POST'])
@bp.route('/stock/stock/', methods=['GET', 'POST'])
@login_required
def stock():
    stocks = Stock.query.order_by(Stock.id.desc())# this gives order of results
    forms = []
    def get_forms(offset=0, per_page=25): #this function sets up the number of
        return forms[offset: offset + per_page]  #results per page
for stock in stocks:
    form = AddStockForm()
    form.id.default = stock.id
    form.image.default = stock.image_url
    form.date.default = stock.date
    form.description.default = stock.description
    form.event.default = stock.event
    form.achat.default = stock.achat
    form.vente.default = stock.vente
    form.sold.default = stock.sold
    forms.append(form)
for form in forms:
    if form.validate_on_submit():
        if form.modify.data:
            stock = Stock.query.filter_by(id=form.id.data).one()
            stock.date = form.date.data
            stock.description = form.description.data
            stock.event = form.event.data
            stock.achat = form.achat.data
            stock.vente = form.vente.data
            stock.sold = form.sold.data
            db.session.add(stock)
            db.session.commit()
        elif form.delete.data:
            stock = Stock.query.filter_by(id=form.id.data).one()
            db.session.delete(stock)
            db.session.commit()
        return redirect(url_for('stock.stock'))

    #this is the code from the link that I used to paginate
    page, per_page, offset = get_page_args(page_parameter='page',
                                           per_page_parameter='per_page')
    total = len(forms) # this code counts the resulting list to be displayed
    pagination_forms = get_forms(offset=offset, per_page=per_page)
    pagination = Pagination(page=page, per_page=per_page, total=total)
    form.process()  # Do this after validate_on_submit or breaks CSRF token

return render_template('stock/stock.html', title=Stock, stocks=stocks
                       page=page, forms=pagination_forms, per_page=per_page, pagination=pagination)
#And finally this is the pagination passed to the html

所以，这是给所有像我这样与一切抗争但仍然热爱一切的人的

        return forms[offset: offset + per_page]  #results per page

    forms.append(form)

            db.session.delete(stock)
            db.session.commit()
        return redirect(url_for('stock.stock'))

    #this is the code from the link that I used to paginate

return render_template('stock/stock.html', title=Stock, stocks=stocks
                       page=page, forms=pagination_forms, per_page=per_page, pagination=pagination)
