I try to get all the data using the name field that I specified in the api request body. I've created a filter for the .find() function. But I can't get any results (response body shows null, no error at all). You can see my model file and the rest of the code at the bottom.
Controller:
func get_formbypatientfullname(ctx *gin.context) { col := mongodb.client.database(config.database_name).collection("consentforms") filter := bson.m{"patient": bson.m{"name": ctx.query("name")}} cursor, err := col.find(_context.todo(), filter) if err != nil { log.fatal(err) } var results []general_models.consentform if err = cursor.all(_context.todo(), &results); err != nil { log.fatal(err) } for _, result := range results { res, _ := json.marshal(result) fmt.println(string(res)) } ctx.indentedjson(http.statusok, gin.h{"data": results}) }
Model file:
type ConsentForm struct { ID primitive.ObjectID `json:"_id,omitempty" bson:"_id,omitempty"` FormFileURL string `json:"FormFileURL" bson:"FormFileURL"` ProcessName string `json:"ProcessName" bson:"ProcessName"` DateOfNotification string `json:"DateOfNotification" bson:"DateOfNotification"` WitnessName string `json:"WitnessName" bson:"WitnessName"` WitnessSurname string `json:"WitnessSurname" bson:"WitnessSurname"` ResponsibleDoctor string `json:"ResponsibleDoctor" bson:"ResponsibleDoctor"` Patient IPatient `json:"Patient" bson:"Patient"` QuestionOptions IQuestionOptions `json:"QuestionOptions" bson:"QuestionOptions"` AdditionalDetails string `json:"AdditionalDetails" bson:"AdditionalDetails"` } type IPatient struct { // ID primitive.ObjectID `json:"_id,omitempty" bson:"_id,omitempty"` Name string `json:"Name" bson:"Name"` Surname string `json:"Surname" bson:"Surname"` Birthdate string `json:"Birthdate" bson:"Birthdate"` TCKN string `json:"TCKN" bson:"TCKN"` FacePhotoURL string `json:"FacePhotoURL" bson:"FacePhotoURL"` SignatureImageURL string `json:"SignatureImageURL" bson:"SignatureImageURL"` }
I try to filter based on username and get all the data of the user. But I think I have a bug in the filter part or the whole code because I can't get any data back. What I get in return is empty.
Correct answer
Your filter will match where patient
is an embedded document and has a single name that matches the given value
Documentation of the field.
To filter by a field embedded in the document, you must use dot notation:
filter := bson.M{"Patient.Name": ctx.Query("name")}

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
