Question

我在模板中有一个表单，用户可以在其中输入地址。我想使用Google API应用“地方自动填充地址”。

但是，由于某种原因，自动填充功能不适用于表单。任何建议都会被贬低。谢谢。

Forms.py

options(stringsAsFactors=FALSE)
library(XML)

#get website
tfile <- tempfile()
download.file("http://cepea.esalq.usp.br/frango/?page=379&Dias=15", tfile)
temp <- readHTMLTable(tfile)

#read in table
tbl <- temp[[5]][!is.na(temp[[5]]$V2) & !is.na(temp[[5]]$V4),]
tbl2 <- split(tbl, cumsum(tbl$V1==""))[[2]][-1,]
tbl2 

#perform formatting
colnames(tbl2) <- c("Date","Price","Pct1","Pct2")
tbl2 <- data.frame(apply(tbl2, c(1,2), function(x) {
    x <- gsub("Â","",x)
    x <- gsub(",",".",x,fixed=TRUE)
    x <- gsub("%","",x)
}))
tbl2$Date <- as.Date(tbl2$Date,"  %d/%m/%Y  ")
tbl2$Price <- as.numeric(tbl2$Price)
tbl2$Pct1 <- as.numeric(tbl2$Pct1) / 100
tbl2$Pct2 <- as.numeric(tbl2$Pct2) / 100
tbl2

Html模板

where_load = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'id':"autocomplete"}))
where_unload = forms.CharField(max_length=100, widget=forms.TextInput(attrs={'id':"autocomplete"}))

在回调中，找到要应用自动填充功能的元素，然后在那里声明自动填充功能。您也可以在模板中加载api密钥，就像我在下面所做的那样

<script>
    var onLoaded = function() {
       // I am assuming your field has id of where_load, it might be different
        var location_input = document.getElementById('where_load');
        var autocomplete = new google.maps.places.Autocomplete(location_input);

    }
</script>
<script src="https://maps.googleapis.com/maps/api/js?key={{api_key}}&libraries=places&callback=onLoaded" async defer></script>
