我正在編寫一個已經用Python/Django編寫的項目，並且在其中一個網頁上，有一個表格顯示一些關於數據庫中對象的信息。Python/Django-如何更改在模板中顯示的信息？
該表格顯示在「標籤式內容」元素中，並且每個標籤顯示不同的表格。每個表格中顯示的信息都不相同（即表格具有不同的列），具體取決於它顯示的對象的類型。
我想從這個「標籤式內容」元素中的一個表中刪除一列。
的view用於返回該網頁的URL與定義：
def report_ccis(request, project_id):
""" CCI items styled for pdf """
print "report_ccis() called in costing.views (1463) "
project = Project.objects.get(id=project_id)
budget = get_current_budget(project_id)
cci_total_exc = budget.cci_total_exc_vat_final
cci_grouped_items = budget.cci_items.all().order_by('project_room', 'name')
context = {
'project': project,
'cci_total_exc': cci_total_exc,
'cci_grouped_items': cci_grouped_items,
'webview': 1,
}
try: context['current_budget'] = project.budget_versions.get(current_marker=1) #For option name/date on top of pdfs
except ObjectDoesNotExist: pass
if request.GET.get('stage') == 'pd':
print "request.GET('stage') == 'pd' "
""" Render post deposit homepage """
context['html'] = render_to_string('costing/report2_ccis.html', context)
print "'render_to_sting() called with parameter: costing/report2_ccis.html "
context['active_tab'] = '4'
print "render() called with parameter: costing/reports_post_deposit.html "
return render(request, 'costing/reports_post_deposit.html', context)
else:
print "request.GET('stage') != 'pd' "
""" Render pre deposit homepage """
context['html'] = render_to_string('costing/report_ccis.html', context)
print "'render_to_sting() called with parameter: costing/report_ccis.html "
context['active_tab'] = '5'
print "render() called with parameter: costing/reports_pre_deposit.html "
return render(request, 'costing/reports_pre_deposit.html', context)
的view要麼返回「reports_post_deposit.html」，或取決於由request類型「reports_pre_deposit.html」，並且在這兩個頁面上，這當前都會在「標籤式內容」區域中顯示一個表格，列標題爲「項目」，「初始金額」，「最新金額」&'注意'。
我想要做的是從'reports_pre_deposit.html'頁面的表格中刪除'Latest Sum'列，但我不確定如何在Python/Django中執行此操作改變Django的HTML文件，或通過改變Python view？
多數民衆贊成在傳遞給render_to_string()的report_ccis.html文件是：
{% extends "pdf2_base.html" %}
{% load money_handling %}
{% block web_content %}
{% block content_overview %}
{% endblock content_overview %}
{% block content_construction %}
{% endblock content_construction %}
{% block content_schedule_of_works %}
{% endblock content_schedule_of_works %}
{% block content_report_by_class %}
{% endblock content_report_by_class %}
{% block content_ccis %}
{{block.super}}
{% endblock content_ccis %}
{% block content_payment_schedule %}
{% endblock content_payment_schedule %}
{% block agreed_variations %}
{% endblock agreed_variations %}
{% block agreed_variations_client %}
{% endblock agreed_variations_client %}
{% block agreed_variations_construction %}
{% endblock agreed_variations_construction %}
{% block unagreed_variations %}
{% endblock unagreed_variations %}
{% endblock web_content %}
編輯 我修改了HTML，包括新的塊，作爲建議：
{% extends "pdf2_base.html" %} {#ERF(02/12/2016 @ 1150) Change from 'pdf_base.html - to ensure it displays all relevant variables. ' #}
{% load money_handling %}
{% block web_content %}
{% block content_overview %}
{% endblock content_overview %}
{% block content_construction %}
{% endblock content_construction %}
{% block content_schedule_of_works %}
{% endblock content_schedule_of_works %}
{% block content_report_by_class %}
{% endblock content_report_by_class %}
{% block content_ccis %}
{{block.super}}
{% endblock content_ccis %}
{# Set the block to content_ccis_pre_deposit) #}
{% block content_ccis_pre_deposit %}
{{block.super}}
{% endblock content_ccis_pre_deposit %}
{# Add details that are displayed in report2_ccis.html here too #}
{% block content_payment_schedule %}
{% endblock content_payment_schedule %}
{% block agreed_variations %}
{% endblock agreed_variations %}
{% block agreed_variations_client %}
{% endblock agreed_variations_client %}
{% block agreed_variations_construction %}
{% endblock agreed_variations_construction %}
{% block unagreed_variations %}
{% endblock unagreed_variations %}
{% endblock web_content %}
但是當我現在嘗試要在瀏覽器中顯示頁面，我收到一條錯誤消息：
TemplateSyntaxError在/成本/ 5547 /報告/ CCIS/
，並強調該行：
context['html'] = render_to_string('costing/report_ccis.html', context)
的問題......我不知道爲什麼，這是造成問題？
末編輯
，我想刪除將由行中顯示的列：
{% block content_ccis %}
{{block.super}}
{% endblock content_ccis %}
但這也什麼都會顯示這是我想要的columns-其餘
{% extends "costing/reports_tabbed.html" %}
{% load staticfiles utilities %}
{% block title2 %}
| Pre-deposit reports
{% endblock title2 %}
{% block page_title %}
<a id="topbar-shortcuts" data-view-url="{% url 'hub:open_sidebar' %}?app={{app.name}}&p={{project.id}}&po=1">
<span class="m-l-md">Reports</span> <img class="icon open text-sm m-l-md" src="{% static 'img/down-lt.png' %}" >
</a>
<div id="topbar-results" class="{{app.color}}" style="display:none;"></div>
{% endblock page_title %}
{% block tabs %}
{% with 'Overview, Construction budget, Schedule of works, Client choice items'|listify as tabs %}
{% for tab_name in tabs %}
{% with forloop.counter as tab %}
{% if not tab == active_tab|add:0 %}<a class="tab" href="{% url 'costing:report_tabbed' project.id %}?tab={{tab}}">{% else %}<a class="active tab">{% endif %}{{tab_name}}</a>
{% endwith %}
{% endfor %}
{% endwith %}
{% endblock tabs %}
的reports_pre_deposit.html文件本身與定義
我將如何從行{{block.super}} ...刪除列？或者我需要從正在呈現此HTML的view或HTML文件本身中刪除它？
我試着查看傳遞給report_ccis(..)視圖中的context變量的參數，但這些參數似乎都沒有設置表中顯示的列。
任何人都可以指出我將如何/在哪裏更改顯示的列？

從pdf2_base.html的block的HTML文件extend，其中顯示的表是：
{% block content_ccis %}
{% if not webview %}
<table>
<tr>
<td>
<a class="plain-link" href="{% url 'costing:home' project.id %}">Client Choice Items - please refer to 'Budget Explained' </a>
</td>
<td rowspan="2" style="text-align: right;">
</td>
</tr>

<td>
<span class="project-name">{{project.project_name|upper}}</span>
</td>
</tr>
</table>
{% endif %}
<table class="pdf-report left">

<tr class="last-row">

<td colspan="3"></td>

</table>
<p>To help you understand the rationale behind these items, please refer to booklet 'Budget explained'. </p>
{% endblock content_ccis %}
如果我評論了 '最新的總和' 表<!--th>Latest sum (£)</th-->標題，這顯然從表格中刪除標題，但我不知道該如何刪除顯示在該列中的值，最後只是將「註釋」列標題向左移動一下，以便現在位於上方「最新總和'值和'註釋'列不再有標題。
有沒有一種方法可以根據表格是顯示pre-deposit還是post-deposit數字，還是需要爲每種情況編寫單獨的HTML塊？

的(% block content_ccis %}部分現在看起來是這樣的：

更新的觀點是：
def report_ccis(request, project_id):
""" CCI items styled for pdf """
project = Project.objects.get(id=project_id)
budget = get_current_budget(project_id)
cci_total_exc = budget.cci_total_exc_vat_final

context = {

'webview': 1,
}
try: context['current_budget'] = project.budget_versions.get(current_marker=1) #For option name/date on top of pdfs

我不確定你是什麼意思？這個「塊」是顯示網頁上標籤內容的「CCIs」選項卡上的所有內容 - 當前有四列顯示 - 我仍然想要顯示其中的三個，只刪除一個。如果我不渲染'block.super'，那麼該選項卡上的所有內容都會消失... – someone2088
對不起，也許您可以在父模板中有兩個不同的塊，根據您在上下文中發送的變量渲染塊。 {％block content_ccis％} {{block.super}} {％endblock content_ccis％} {％block content_ccis2％} {{block.super}} //此顯示沒有最後一列 {％endblock content_ccis2％} – rsb
