General way of iterating over a dictionary containing multiple mpld3 graph images in Django?
问题
我正在进行一个个人项目。其中的一部分是在网页上显示多个直方图。到目前为止，我已经能够使用以下代码使其工作：
views.py：
import pandas as pd
import matplotlib.pyplot as plt, mpld3
import scipy.stats as stats
import numpy as np
def histogram_plot(request):
context = {}
df = pd.read_csv(test_file) # 使用pandas读取
for column in df.columns:
fig = plt.figure()
plt.hist(df[column])
histogram = mpld3.fig_to_html(fig)
context[f"{column}Histogram"] = [histogram]
return render(request, "base.html", context)
base.html：
{% for elem in context %}
{{ context[elem]|safe }}
{% endfor %}
我在网页上看到了所有的直方图，但问题是所有的HTML代码都使用了字典中的硬编码键。
是否有一种通用的方式可以使用for循环来编写我在这个HTML代码中编写的内容，而不是硬编码字典中的键？如果有人能告诉我如何做到这一点，我将不胜感激。

I am working on a personal project. One part of this is to display multiple histograms on a webpage. So far, I have been able to get this to work using the following code:
views.py:
import pandas as pd
import matplotlib.pyplot as plt,mpld3
import scipy.stats as stats
import numpy as np
def histogram_plot(request):
context={}
df = pd.read_csv(test_file) #Read using pandas
for column in df.columns:
fig=plt.figure()
plt.hist(df[column])
histogram=mpld3.fig_to_html(fig)
context[f"{column}Histogram"]=[histogram]
return render(request,"base.html",context)
base.html:
{% for elem in PregnanciesHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in GlucoseHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in BloodPressureHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in SkinThicknessHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in InsulinHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in BMIHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in DiabetesPedigreeFunctionHistogram %}
{{elem|safe}}
{% endfor %}
{% for elem in AgeHistogram %}
{{elem|safe}}
{% endfor %}
I do see all the histograms on my webpage, but the problem is that all of the HTML code uses hardcoded keys in the dictionary.
Is there a general way of writing what I wrote in this HTML code, using a for loop, without hardcoding the keys from the dictionary? I would appreciate it if someone could tell me how to do that.

尝试这个：
def histogram_plot(request):
context = {}
df = pd.read_csv(test_file) # 使用pandas读取
hist_list = []
for column in df.columns:
fig = plt.figure()
plt.hist(df[column])
histogram = mpld3.fig_to_html(fig)
hist_list.append([histogram])
context["hist_list"] = hist_list
return render(request, "base.html", context)
{% for histogram in hist_list %}
{% for elem in histogram %}
{{ elem|safe }}
{% endfor %}
{% endfor %}
这只是将所有的直方图附加到一个列表中，然后在您的模板中对它们进行循环。
英文:
Try this:
def histogram_plot(request):
context={}
df = pd.read_csv(test_file) #Read using pandas
hist_list = []
for column in df.columns:
fig=plt.figure()
plt.hist(df[column])
histogram=mpld3.fig_to_html(fig)
hist_list.append([histogram])
context["hist_list"] = hist_list
return render(request,"base.html",context)
{% for histogram in hist_list %}
{% for elem in histogram %}
{{ elem|safe }}
{% endfor %}
{% endfor %}
This simply appends all your histograms to a list and then loops over them in your template.
